Spiderwire Ultracast Invisi-Braid vs. PowerPro [ULTIMATE REVIEW]


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 4 core factors that I have tested for these lines:

  1. Casting Distance
  2. Abrasion Resistance Strength
  3. Knot Strength
  4. Long-Term Durability (1.5-year update)

See below for the results for each of the 4 tests:

1. Spiderwire Vs. PowerPro Casting Distance

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

SpiderWire vs. Power Pro Distance Measuring

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

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

However, the results for both the lightweight and heavyweight 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 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.

After using these two lines for over 1.5 years, I can now confidently comment on how each brand has held up over time.

On day one, Spiderwire was my favorite because it cast a little bit farther than PowerPro.

However, I noticed that my casting distance quickly decreased with Spiderwire the more I used it, whereas my casting distance with PowerPro stayed the same (and maybe even increased) the more I used it.

My casting distance decreased with Spiderwire so much so that I didn’t even enjoy using it anymore because I could tell how much less distance I was covering.

The reason this happened, I believe, was that the Spiderwire has a waxy exterior, which helped it cast so far on day one.

But when the wax coating was gone (which, in my case, happened pretty quickly), the casting distance decreased.

So in regards to casting distance, I now recommend going with PowerPro over Spiderwire.


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 a 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.

After testing these two lines for over a year and a half, I recommend PowerPro over Spiderwire because of PowerPro’s long-term ability to cast far, and because each brand performed very similar in the other categories.

Have you noticed any clear winner one way or another on any of these important aspects (distance, abrasion, or strength)?

I would like to see one of your scientific reviews of Pandorra Braid (Australian brand) which I am seeing everywhere these days. Its the only brand with color change in 10lb available in tackle shops in my area (Miami). The color change every 30 feet makes depth and casting distances easy to measure and assess.

I’ve been using different braids for years. Now use suffix 832 mostly. Tried invisocast spiderwire, recognized the fuzzy issue lowering distance, so I fixed it with a candle. Cast line in grass with spoon w/o hooks or smooth sinker further than the fuzzy part, take big candle or chunk of beeswax cut a kerf with knife, slide line into kerf, arrange candle so held still (weight or jammed into picnic table brace), crank line on reel, repeat if necessary. Do this as soon as fuzz appears or as part of maintenance. Fuzz gone, line slick as grease. Can cast further than before and line is actually thinner. Can use on other braids. Different waxes work, but beeswax in the mix is best. YMMV, but if the fuzzing of the line happens again, easy to re-wax.

I’ve been using SpiderWire Stealth braid in moss for 20+ years, and have never been disappointed with it. When the Ultracast Invisa-braid came along I decided to give it a try. NOPE!!! That stuff is garbage. First thing I noticed immediately, while trimming the tag end as I was spooling my reel, was how much easier I could cut it. Right then I thought, that can’t be good. Then went fishing with it. I ended up with huge wind knots, and tangles constantly. Never had those issues with the stealth braid. Then I got snagged. With a few good tugs, same knot that I’ve been tying for years without issue, slipped, and my lure was left dangling there on a twig. I was able to retrieve it. Then a while later while casting, the line just snapped. I was casting a small plastic minnow with a small 1/32 jig head on a small #1 jig spinner. The whole set up probably weighed 3/16. Never had that happen with ANY fishing line. Tied on a small 1/4 ounce frog. A few casts later, snapped again. Tied on a small 3/16 popper. A few casts later, snapped AGAIN. That was enough. Went home, and stripped the stuff from my reel, and respooled with stealth.

Luke, could you repeat your distance casting test with the used lines to document the distance loss/gain? Great info once again! Thanks.

What about Suffix? I use that for surf fishing because I found a clearance spool of 1000yds of 30lb for like $80. Never had an issue with it. I like Power Pro too. My favorite braid is Fishingsir’s Godline S series. It is 30% thinner. I was able to put 300yds of 8lb on a 200 size Sienna. It’s so light and thin, it floats down stupid slow. And it’s strong. Never cared for SpiderWire. I always feel like it’s a sales pitch. I remember the old commercials. I wouldn’t consider 3-4 feet a significant advantage.

If doing tests that you did in this example I would change 1 thing especially in the casting test and wet both lines to start. When I did my abrasion tests I did the testing under water. I also do my knot strength testing under water.

Good info on the line test and review . It would also be interesting to compare these two lines to Seaguar Smackdown . While it is expensive , I have found it to be superior especially when the spool is sprayed with Real Magic . I’am kiayak redfishing everyday I can at 68 and I can promise a “ fun and successful slay ride “ with this combination, on a larger slot red. Thanks for the review. ..cd in Beaufort NC

Hi Luke. I’m particularly interested in your distance casting test. I’m curious if you took each reel and swapped them on those same rods you used for the test. The reason being is that all rods are not created equally. Even the same brand and model may vary in performance if the spline of one rod is slightly off, or if the guides are not aligned or set on the blank exactly the same. A rod can offer significantly better performance if the rods are not splined exactly the same.

I’ve been using spider wire invisi braid for many years now. Never have had a problem with it at all. No reason for me to change now but looks like I need to learn the fg knot

I’ve been a Fireline guy in the past, but I just ran out of a big spool of 10lb camo color and was thinking that it was time to investigate some new lines. So great timing on this test. Does anyone have any comments on Nanofil or J Power? I see a lot of ads for these new 8 braid fused lines and I’m wondering if they are worth the hype and price?

Reply to  Jeff Kritzman

In my tests of the original Fireline when it hit the market, it tends to break down, (wear), as you use it. the line appears to get “fuzzy”. This fuzzy appearance creates more friction going through the guides as the line ages, reducing casting distance. Nanofil, in my tests did not have the durability or longevity of Power Pro, neither did Fireline. Are you referring to J-Braid? I’m not familiar with J Power. If it’s J-Braid, I’ve used three versions of it. I’ve used the J-Braid X8, X4, and Grand. Of the three, my preference is the X4. Both the X8 and Grand seemed to have more issues with knotting and breakage. The X4 durability has been excellent, but not quite as good as the original Power Pro, in my opinion.
