PowerPro vs. Spiderwire Ultracast Invisi-Braid

Spiderwire Ultracast Invisi-Braid vs. PowerPro

I have been curious to know if the braid that I’ve been using for the past 10+ years (PowerPro) is any better or worse than other options.

So I decided to start doing some testing in order to know for sure if I’ve been making a good buying decision this whole time or if I need to make a switch.

And since I’m guessing that many other anglers are curious to know unbiased stats on the lines too, I’ll be documenting all of the tests so that you can see exactly what I’m doing and make your own conclusions based on the data.

Many members have asked me to do a review on Spiderwire Ultracast Invisi-Braid, so I decided to make that the first line that I test head-to-head against PowerPro.

Here are the 3 core factors that I’ll be testing for these lines:

  1. Casting Distance
  2. Abrasion Resistance Strength
  3. Knot Strength

First, we’re going to be testing the casting distance to see which one will your carry your bait or lure farther. We’ll then test the abrasion resistance for each line. Finally, we’ll test the knot strength.

My assumption was that PowerPro would win casting distance because it is thinner than the Spiderwire (0.15 mm vs 0.17 mm) as shown by the red arrows on the boxes below.

spiderwire vs power pro

Note: We are purposefully not sponsored by any fishing equipment manufacturers (this all is funded by the Salt Strong Fishing Club members), so there is absolutely no bias at all in these tests.

Our goal in these tests is simply to determine which lines are the absolute best value based on their actual performance without regard to their hype so that we all can get the most bang for our buck when buying our equipment.

Here are the results for the 1st test:

1. Casting Distance Experiment Details

Spiderwire vs. PowerPro

We set up some controls to make sure the results of our tests are as accurate as possible. Here are the factors that we all kept equal:

  1. Both lines are brand new, day one out of the box
  2. Both lines are listed at 10 lb test
  3. Both lines are rigged on the exact same rod
  4. Both lines are rigged on the exact same reel
  5. The casting weights were the exact same size and shape

To keep it easy to see, we have two different color lines. The line colors are the following:

  • White – Spiderwire Invisi-Braid
  • Yellow – PowerPro

The goal of these tests is to determine which line will enable us to cast the farthest.

Casting Distance Test Process

Casting SpiderWire Invisi-Braid vs. Power Pro

For these tests, we decided to do three casts of each line with both a light weight and a heavy weight.

We started at the same point for each cast (marked by a starting line) and cast the lines three times each with the two different weights. We then marked the landing of the weight for each cast with small flags.

Green flags marked where the PowerPro landed and the pink flags marked the same for the Spiderwire Ultracast Invisi-Braid.

I first did this test process using the lighter weight (3/16th oz).

And when it came time to use the heavier weight (1/2 oz) for the 2nd round of the experiment, I switched the lines from one rod to the other to make sure that the individual rods were not affecting the test results at all.

Casting Distance Test Results

SpiderWire vs. Power Pro Distance Measuring

The results for both the light weight and heavy weight casting distance tests are the following:

Light Weight Test

To get these results, I measured the three landing spots of each cast for both lines and figured out the average casting distance of each line.

  • PowerPro average casting distance with light weight: 122 feet
  • Spiderwire Ultracast Invisi-Braid average casting distance with light weight: 126 feet

Heavy Weight Test

I applied the same methods I used in the light weight test to find the average casting distance of each line.

  • PowerPro average casting distance with heavy weight: 200 feet
  • Spiderwire Ultracast Invisi-Braid average casting distance with heavy weight: 203 feet

Casting Distance Conclusion

SpiderWire Invisi-Braid

Our test results found that Spiderwire Invisi-Braid casts farther than PowerPro with both a light and heavy weight.

Between the two tests, Spiderwire Invisi-Braid traveled farther than PowerPro.

But the distance was minimal (within 3.5%) and the spiderwire seems to lose its distance after use making this factor a wash in my opinion.

2. Spiderwire Vs. PowerPro Abrasion Test

spiderwire ultracast invisi-briad vs. PowerPro Abrasion Resistance

For this test, we connected each line to a small weight and hung the lines over sandpaper on our oscillation device, which simulates what the lines would do if they were wrapped around structure such as a bridge piling.

Each line was tested on both sides of the oscillation device to make sure the results were as accurate as possible. We tested the abrasion strength of each line twice.

In this test, the line that breaks second has the higher abrasion resistance strength.

Abrasion Test Video

In this video, I show you the full experiment for the abrasion resistance test for the two lines.

Abrasion Resistance Test Results

Test 1: The Spiderwire Ultracast Invisi-Braid (right side) broke a split second before the PowerPro (left side).

Test 2: The Spiderwire Ultracast Invisi-Braid (left side) broke a split second before the PowerPro (right side).

The Spiderwire Ultracast Invisi-Braid broke literally a split second before the PowerPro during each test.

Although the Spiderwire broke first each time, the PowerPro broke so soon after it that it shows the difference in the two lines’ abrasion resistance strength is minuscule.

3. Spiderwire vs. PowerPro Knot Strength Test

PowerPro vs. Spiderwire braid to braid knot strength test

For this experiment, we decided to test two different kinds of knot strengths for the two lines: braid-to braid and braid-to-leader knot strength.

You can see how we set up the two tests below:

Test 1: Braid To Braid Knot Strength

Spiderwire Ultracast Invis-Braid vs. PowerPro Knot Strength

To test the braid-to-braid knot strength for these two lines, we connected each line to a swivel using the Uni Knot and then connected to the two lines together using the Modified Double Uni Knot.

We then connected the strand of lines at the swivel to a scale. Next, we pulled the scale until one line broke and measured the strength of the line, where it broke and which line broke first.

We did this two times, one time with the scale attached to the Spiderwire swivel and one time with it attached to the PowerPro swivel.

The line that breaks first has the weaker knot strength.

Test 2: Braid To Leader Knot Strength

Spiderwire Ultracast Invisi-Braid vs. PowerPro Braid to Leader Knot Strength

To test the braid-to-leader knot strength for the two lines, we connected each line to a swivel using the Uni Knot. We then connected each line to the same piece of fluorocarbon leader line using the FG Knot.

We then repeated the process we did for the braid-to-braid test.

Spiderwire vs. PowerPro Knot Strength Test Results

The results for the knot strength tests were as follows:

Test 1: Braid To Braid Knot Strength Results

  • Round 1 – The PowerPro line broke first at the Modified Double Uni Knot.
  • Round 2  – The Spiderwire line broke first at the Modified Double Uni Knot.

Winner: Draw

Test 2: Braid To Leader Knot Strength Results 

  • Round 1 – The Spiderwire line broke at the Uni Knot.
  • Round 2 – The PowerPro line broke at the Uni Knot.

Winner: Draw

These lines are almost identical when it comes to knot strength. Both lines held up great when tied with the FG Knot to the leader and had high strength breaking points for each test.

SpiderWire vs. Power Pro Casting Test

When it comes to casting distance, Spiderwire Invisi-Braid proved to outperform the PowerPro when it is brand new out of the box.

But after using the spiderwire for a couple months, it seems as if the casting distance has decreased as the slick outer layer has diminished.

As for abrasion resistance, PowerPro had the slight advantage over the Spiderwire Ultracast Invisi-Braid.

For knot strength, these lines were virtually the same and both had higher knot strength than I anticipated.

I think the main thing to take away from these tests is knowing that both of these tested out to be surprisingly close even though they feel very different to the touch.

I am currently indifferent in chosing between these two lines, so I’m curious to know if have noticed any clear winner one way or another on any of these important aspects (distance, abrasion, or strength).

If you have, please leave a comment below (we aren’t affiliated with either company in any way so your comment will not get filtered out if it’s overly good or overly bad… 100% transparency).

You should pick up a spool of Pure Fishing’s new Amazon brand – Kalex. I’m convinced it’s white label Spiderwire for a 1/3 of the price.

Hi Luke, firstly loved the video and appreciate real of the time and effort you put into these and in a real world situation.

I have been trying out several different Braids for Beach fishing in the UK over the past two seasons during the winter months [its gets down to minus 6 or minus 8 [even -11 deg C on occasions]] and found PowerPro white a very good line to knot and good overall strength even though I think its a little too ‘floppy’ for my personal preference – however – bizarrely I tried the Green PowerPro and it was useless, even a gentle sudden jerk [real life snagging situation using gloves] broke the line in numerous and very place I tried it, and when I tried the exact same line rating in non-Green/Moss I found significant differences in strength of otherwise identical lines but of a different colour.

Also, I recently tried some Fireline 8, smoke, which I found excellent and behaves a little more like mono [stiffer than PowerPro etc] however this was very awkward to knot and the colour coating seems quite easy to migrate when wet which makes knotting even more tricky as it will slip rather than dig in when tying an FG knot [if you test every time to check its acceptable as I do], so this puts me off it even thought [like Nonofil] its very thin and thus helpful in the awful May Weed we have been having recently.

Like some of the other comments I found Nanofil very good for casting distance [Surf casting against high winds with 6oz weights plus bait – usually lug wrapped within a whole squid on a Pennel Pulley rig], very good knot strength, however I found that over the shingle on mixed ground found it doesn’t seem to last too long before it ‘flattens’ and looses strength and of course frays and breaks – so you really do have to keep monitoring it – not helpful when your freezing with cold hands in the dark.

I have tried most of the Spiderwire braids including Code Red, Ultra Casting and Stealth etc variants and found them generally excellent but beware of frays, they seem consistent bu also suffer from migration of their respective additive coatings.

It would be really interring to know if you test different colours [that’s colors to you in the US…:)..], eg. Green/Moss vs Smoke or Translucent/White vs Red of the same braids to see if there are any real variances and if so to quantify what these might be otherwise I would have to assume I have just purchased some ‘dud’ batches.

Thanks again for everything you’d your brother do, have been a fan for a long time.

Best regards – John

Brian Adams

I assume the thin diameter of the line prohibits fish from seeing it but is there any significance in the line color?

Bruce Reid

have you tested Suffix 832?

Mark Ciciulla

Have you tried to measure the casting differences between regular spinning guides and American Tackle “Microwave guides”? Also it would be interesting to see the Fuji K frame guides added to the experiment combined with line conditioners.

Richard Fiorentino

I will stick to Power Pro as I never have a problem with wind knots, so why change?

David Andrews

The more important tests would be between Spectra (Power Pro, Spiderwire) lines and Dyneema (Fireline) lines. I like and use both, but there are noticeable differences. Dyneema lines get fuzzy faster, but when fuzzy are still strong. When Spectra lines get fuzzy, they are about to break. Either getting fuzzy can make air knots form easier. I use some mono for filling a spool and feel comfortable reversing the old fuzzy Dyneema line to get the “new” line out front.

Randal Jones

Thanks Luke. Lots of time and effort. Really do appreciate it. Granted the outcome was not so dramatically different this time but we’ve seen it when it was with other products. Thank you again. You guys are the best.

Bill Bohler

A few years ago I switched from PowerPro to Nanofil. I did that because you have to really try to get a wind knot in the Nanofil. I probably could count on one hand the number of rimes that happened over that two year period, and I fish a lot. Also with a much smaller line diameter and “slicker” finish the Nanofil adds a lot more distance.
The only negatives I have found are the price and being limited on the knots that work. With the FG knot that problem is eliminated.
I would love to see you compare Nanofil to another premium braid.

Will Hahn

I used to use spiderwire on everything and have since switched to power pro on almost all of my set ups. The biggest advantage I have seen, personally, is that the power pro is much less susceptible to wind knots- and that when it does happen, the power pro seems to be easier to untangle- the power pro seems to stay stiffer when pushing the line back through the knot, whereas the spiderwire seems to expand/unravel more under pressure when doing so. This wasn’t a parameter in your test, but it’s the biggest difference that I’ve noticed. Spiderwire always did well for me in every aspect with the exception of knotting up. I still have spiderwire in one setup, and on the last trip I took with all of my rods (friends were using some) the one with the spiderwire knotted up 3 times that day on one rod vs 0 on the other 4 strung with power pro. It was not a controlled test; different rods/reels and line weights (30lb spiderwire vs 20lb or less on power pro), but I still think that says something. I don’t know if there’s any truth to this and have not validated it myself, but I was told once that the reason for this is that spiderwire is actually flat whereas the power pro is round. That could very well be hearsay and I know my evedence is anecdotal, just sharing my .02. Interested to hear what others have experienced on this subject. Great test guys, keep it up!!!

Jack Noor

Have you ever tried Nanofil? It’s very slick and same diameter as braid .006

I think it casts farther but haven’t tried an abrasion test between them.

Bill Bohler

I use Nanofil exclusively. I have even gone to 5lb. Test and not had an abrasion problem.
It’s almost “wind knot” free and casts forever.
Expensive, but worth it!
Bill Bohler

Marko Rodriguez

Hey Bill, how does its strength compare to 8 strand braids?

Ed Northuis
Ed Northuis

Thanks Luke. What is your opinion on the width of the line as far as underwater visibility and catching more fish?

Gary Rankel

Good stuff, Luke…..hope a PP vs Sufix 832 is next. I love the new 10lb 832.

Marko Rodriguez

Suffix is awesome from my experience. I use 15lb 8 stand and haven’t had any issues and pulled various big fish from reefs and the beach. Looking forward to seeing a comparison

Mitchell McLeod

Thanks for the great videos. I’m Team Power Pro only because the Spiderwire seems to fray a little which annoys me.

Would like to know if you have any opinion on Fins Windtamer sold at Southeastern Tackle.

Scott Walker

Yes I’d like to know any opinions on the Fins Windtamer as well

Michael Danek

Were the lines wet during the testing?

Roger Meyer

I really appreciate your attention to details, accuracy, and details Luke.

Tony McCullock

Luke thanks for the tests you do. The information is very helpful. Try the Daiwa J-Braid x 8. I started using this line a few years ago and really like it. It is similar to Power Pro Super Slick but I think it performs better and is cheaper. Although I have not done any controlled tests?

John Martin

I like the solder ultra casket only because I get it on sale for 30% cheap and have 5 package now. FG knot all the time now for 6 ft mono or fluorocarbon . Use artificial all the time. Best thing for me was practice casting an hour a day for 7 weeks up north here in a church parking lot aimed at targets . I now cast under docks.

Robert Bulla

Luke I’ve used both lines and prefer the Spider Wire, I think SW casts better and less wind knots, so thats what I use. Thanks for the videos.

Dan Friberg

What do you guys have to say about the line lubes that you spray on your reels ? Do you think it helps the line make longer cast and prevent wind knots ? Love SS !!!

Dave Otte

I am a solid believer in Real Magic for reducing wind knots. I don’t think it improves my distance, but I have had very few wind knots since using it. The wind knots I have had pulled out quite easily.

Dan Friberg

Thanks ,I will pick some up . Hate the wind knots !!!

Dave Otte

Get the big spray bottle at Academy. Apply liberally before fishing and after you rinse your reel! It’s worth the cost. Tony did a review of it a while back.

Phillip McCoy
Marcus Lane

You are absolutely correct. I got bad info from a video I watched after seeing Luke’s post. I would actually like to delete my comment but am unable to. Maybe Luke can give me guidance on how to delete it. Beware though, there was a knockoff brand out there. My bad for not checking the date the video was made (5 years ago).

Heber Simmons Jr

Have you compared Berkeley Fireline with Power Pro line? If not,!what are your feelings about these 2 lines?

Paul Turner

Hey Luke,I love all the tests you conduct. I have used the Ardent Gloss line for a couple years. The only negative for me is it’s abbrassion resistance . Depending on the conditions I may use gloss due to the casting distance. It’s like thread . 18# has a diameter of. 14mm. 150 yards cost 15 bucks. Berkley Nanofil is my primary “go to line”. Some people say it’s like dental floss, but I have found it performs well and works great in almost every situation. I have used Power Pro,and still do occasionally, but I love NanoIil from Berkley. I am a member but I guess I wasn’t signed in. So here is my name and email address. To jog your memory, I mailed you some info on the Shimano Stradivarius reels. Thanks for all that you and Joe do.


Hey Luke, I love all the testing you are doing with the many fishing products available to us. There is a fairly new line on the market that I have never heard mentioned….or tested. It is called Gliss, made by Ardent. Just for the heck of it, I bought a spool of the 18 pound test, and have been fishing with it for a short while. I would love to hear your take on it. All I know so far is that it casts WAAAAAAY further than my 10 lb. Power Pro. I don’t mean just feet further. I’m talking many YARDS! Would love to see testing done on knot strength, line breaking strength, abrasion resistance, etc.


David, true Gliss casts far. Problem is if line touches fins, gills, teeth…line breaks very easy.


Anonymous, I believe you are right about that. I remember a couple times I had snook on, and almost immediately the line went slack, and I reeled in my line with nothing on the end of it….not even my leader line. I thought I must have had a nick in the line, but it may have been dragged across an oyster or something. Too bad. Because I really like the distance this stuff achieves.

Gary Rankel

So many lines to test (my go-to is the Sufix 832). I’m more interested in abrasion resistance than slight differences in distances.

Bill Bohler

How about doing a comparison using Berkley “Nanofil” ?
I have gone to it for everything in shore, and love it.
Bill Bohler


As you know, there are many variables that come into play when maximizing the casting distance. The
3.5% difference is small and could be the result of other variables not considered. And when you consider line diameter, your results are even more surprising…does one line have more frictional
drag than the other; were the lines wet or dry?

Identical reels do not mean equal performance, e.g. lubrication. Although painful, the results might become clearer if the test was repeated using the same reel and rod. It would require unspooling and respooling the reel.

You might repeat the test based on reel fullness versus equal line lengths. Equal line lengths
and reel fullness would require the PowerPro have a backing to fill the spool since it is the lesser diameter. But then, how do we measure fullness? And
does the existence of backing affect casting distance?

Does changing reel type affect the results? Your test used two spinning reels. What if the reel were a low profile baitcaster or a barrel baitcaster?

Marjorie Bray

Thanks again for the time and effort put into these tests. If you haven’t started the knot testing yet, please include the fg with the spider wire. I’m not sure what’s going on with my one rig spooled with Spider wire. I’ve noticed that I’ve been losing my leader an inordinate amount of times. Not so with the rigs spooled with Suffix. My fg knot has been fine till this new rig with Spider wire.

Jeff Chancellor

Hey Luke, i was really curious when I got the email as I typically don’t use PowerPro any longer as my braid. I usually use FINS original or windtamer up here in North Carolina. But what really makes the difference is how I setup the rods. Lighter lures get 10# braid for 1/8 to 1/4 oz soft plastics on jig heads while the heavier lures get 15-20# braid for the big topwaters or hardbaits like Skitterwalks. And if fishing docks, then I have one rod with 30# braid.

it will be interesting to follow your testing. Great videos from Salt Strong keeps us adapting for better results.


Nick Nemeth

I’m also very interested in the power pro max cuatro tests. Can something so close in diameter really be twice as strong, cast as far (or close enough), and hold up over time?

Nick Nemeth

The last time I added new line to my reel I used 10 lb O’hero Adrenaline. Seemed great as new but as Luke questions these lines over time in the conclusion, I don’t think this VERY expensive line has held up very well. I lost a lot of casting distance with it in a very short amount of time. Probably going to stick with power pro again in the future unless more tests continue to favor the spider wire. Thanks for the best videos Luke / Saltstrong! Nobody actually knew what they were buying before you gave us these true comparisons.

Nathan Durfee

What about comparing power pro vs power pro super slick 8. Would love to know how they compare. I’ve ran both and found the slick 8 didn’t seem to cast as far though it was on two different reels.

Richard Fiorentino

I assume you still are using Power Pro and have been satisfied with it.

Scott Thomas

Luke, can you try a test using 20# Power Pro Maxcuatro vs. 10# regular Power Pro. Only .001 difference in diameter with twice the breaking strength. Have to get Maxcuatro online, I haven’t seen it in any store.

William Stadelmeyer

Was that the standard PowerPro or the Super Slick? I find the Slick version casts about 5 to 10 yards farther than the regular PowerPro. That might put it 10 to 15ft past the spider wire. The SuperSlick slips off the hook if tide directly to the hook. I’ve had no problems tying a leader to it.

Trey Senterfitt

I’m glad you thought about trying after they’ve been used a bit. Thus far, the difference appears negligible. I’ll stay tuned!
