High-priced lines lead you to believe they are more abrasion resistant, they are stronger, and invisible underwater because that’s what all the marketing claims.
We’re going to test all THREE factors in today’s test and then you can be the judge.

Leader Line Basics
Why do you even need leader line in saltwater fishing?
First, abrasion resistance.
Leader line attaches directly to your hooks and lures which is where abrasion occurs most.
You also want leader line that is not visible to the fish.
Braid into leader is absolutely the way to go for inshore saltwater fishing.
Abrasion Test
Luke started out depending 100% on fluorocarbon leader.
He then realized he was losing out on a lot of snook.
They have tough jaws that are prone to rubbing through leader line.
The assumption then was to use a thicker leader line to prevent this.
Turns out, that isn’t necessarily true.
In this abrasion test, we put 15lb monofilament leader against 20lb fluorocarbon leader.
The reason for the difference in the two lines is because fluorocarbon is almost always thinner in diameter.
If even after this test you still want to rely on fluorocarbon, we would recommend to buy the bulk spools.
Knot Strength
In our previous knot strength tests, the 20lb fluorocarbon did beat the 15lb monofilament.
Additionally, we debunked another inshore fallacy – using saliva to cinch down knots.
All knots without added saliva performed better than those with saliva.
Invisibility
Neither mono or fluoro are truly invisible.
The science behind fluorocarbon being ‘invisible’ is that the material is a bit denser.
Meaning it’s density is a bit closer to that of water which is supposed to take away the refraction of light.

First, I am too cheap to buy flouro, I would rather have another rod or a boat for that matter. After all these years, why is this still a discussion? Yes, that is rhetorical, it is about the money. Thanks for putting out facts so people can make an informed decision.
I’ve been using just mono most of my life with fantastic results. I personally debunked the myth years ago when I kept losing my snoods in shingle conditions. I normally use a 60-80lb shock leader with 40lb mono trace and 20lb snoods without them failing.
I would have never thought the mono would be the winner. Thank for doing and showing those test results. Keep it up.
That’s an eye opener and a money saving set of results! Thank you!!
Thanks guys
Awesome good to know
Appreciate the info.
Thank Y’All so much for this valuable info.
Great info guys! Is it true that fluoro sinks and mono floats? Also, does mono have more memory?
Thanks
I’ve watched most or all of these tests. Great stuff. Thank you.
