Best Spectra Fishing Line Knots
If you were to ask twenty different fishermen about their favorite spectra connections (spectra fishing line), you’d probably get twenty different answers. But if you were to ask those same fishermen how much testing they did before choosing their favorite, the answer would be little to none. Most simply trust whatever knot they first learned or rely on the recommendation of someone they believed to be an authority on the subject.
I did the same thing and the first ten years I fished spectra I used a bulky uni-knot to connect my spectra to fluorocarbon and while I rarely experienced a failure, the knot wasn’t optimal. About five years ago, I switched to the Tony Pena knot and believed that I’d finally found the best balance between knot strength and fish-ability. Well, that proved short lived as I watched the knot fail repeatedly on a line testing machine. I’ve now moved on to two new knots and both of them are rated as near 100% and are compact enough to be cast without hanging up. Before I get to those I want to share the best knot for splicing spectra.
The Uni Splice knot is not a 100% knot but is rated at 90% which is plenty when it comes to splicing spectra. If you’re using 80# test spectra (spectra extreme braid 80#) you’d need to apply 72-pounds of pressure to break this knot and if you’re pulling that hard other things are probably going to break first.
As you can see, the knot is very small and can be cast through your guides without hanging up but is annoying. If I need to use this knot to take out a bad spot in my spectra during a trip, I will replace at least 100 yards of line when I get home so that the knot is on the spool and not going through the guides the next time I fish.
The first spectra to fluorocarbon knot I use is for hollow spectra and requires some tools to tie but is pretty much a 100% knot. I wrote a full article about the knot, including a video of how to tie it, if you haven’t already seen it you’ll want to click here and watch it before proceeding or the next video won’t make sense. In this video I’ve made a modification to the original knot to make it more inshore fishing friendly.
The next spectra to fluorocarbon knot is another 100% knot that is used for solid (or hollow) spectra. This knot can be tied without any special tools and casts through the guides well so you can get away with a longer fluorocarbon leader when inshore fishing without having it hang up and affect your casting (inshore fishing techniques).
When tied correctly this knot is clean and minimal. When tied incorrectly it will always fail when it’s being tied, so if it comes out tight and looking correct, you can trust that it’s going to hold up.
While these are probably different than your trusted knot, I recommend giving one or all of them a shot as they’ll serve you well on the water.
