No matter which brand of fluoro I use, I always somehow get a break in the middle of my spool. I've lost countless lures by casting and watching the lure and the line fly into the lake.

Now let me say that I'm not the best caster in the world...I don't get birds nest, I get eagles nests about once a trip on one of my reels. I do string my reels under tension and I don't let loose string stay loose inside the reel (as long as I see/feel it in time).

Does anyone else have this problem? Anyone know what's causing this for me?

i would bet it's the backlashes. Floro line is VERY brittle and a tiny kink can cause it to snap. That stiff floro line may also be why you're having trouble casting. It's so stiff it can unspool itself. If you want sensitive line check out some P Line CXX copolymer. It's stronger than floro and much more limp, easier to cast too.

Try High Seas copolymer, know exactly what your talking about

Does Copolymer have the same benefits as fluoro?

This is why I also switched to P-Line Copolymer..

Don't give up on flourocarbon line. Get a good one, like InvisX, it will be soft enough to make casting easy. And strong enough to feel confident with it.

I've been using it, in 15lb, to flip and pitch HEAVY weeds lately on a Falcon Amistad. Good stuff.

But, yes, the backlashes are probably causing the kink in the line. Also could just be a bad spool of line.

If you get hung up, don't put the pressure of the break off on the spool. Fluoro will cut into itself and create weak spots. Before I figured this out, I had the same problem. Since I figured it out, I've never had that problem.

I've been using InvisX and Sniper, both with the same issues. I've also used some other random brands just to give them a try, and the same thing.

And it's not just 1 spool of line, it's many spools.

It's possible that you don't have your reel adjusted correctly, and they way you cast can also cause issues.

Sounds like its getting knicked somehow. Could be your reel or possibly your rod guides that damages the line a tiny bit here and there.

Well. If it's many different brands, and spools of flourocarbon, then it's obviously not the line. I'd look at the reels for burrs on the level wind and look at the rod guides for wear. Something is causing the line to get weak spots. List of reasons that flourocarbon breaks.

1. Really big fish and hard hookset with a single looped line tie
2. Abrasion cuts on the line that go unnoticed until it's too late
3. Using far too small of a weight line for the application
4. Line dig in the spool from a previous hard hookset that causes a kink/weak spot
5. Over stretching under weighted line
6. Severe backlashes causing knot kinks in the line
7. Bad spool of line.

These are the "line related" problems.

The rod and reel can also be major issues too. If the rod tip is missing an insert, it will link the line on a hookset, then the next cast it can break where the link was. A bad guide insert anywhere on the rod can cause abrasion nicks leading to broken line (had this happen on a StCroix that was brand new).

Like I said. Don't give up on the line. I use it everyday on every reel that I own that isn't a braid setup. I simply never have these issues. And I backlash on occasion. Just not the huge nests your having. I actually have more backlashes flipping and pitching with flourocarbon. The trick is to straighten it out ASAP. And not pull on the line when doing so.

Run a q-tip along each of your guides on your rod and if it pulls anywhere, you have another problem and it's not the line. Is this happening on different set-ups?

Likely casting with a loop in the spool

If you get a bad kink in fluourocarbon you might as well cut everything above it because at some point it is going to break. I would bet your problem has to do with kinks caused by backlashes.

I honestly think its better than fluoro. It sinks, it's very limp, and it's very sensitive as well. I use it for almost all of my single hook presentations. Plus it's limp enough that you can crank with it, throw spinner baits on it, pretty much any moving bait. And the thing that I love the most, it stretches way less than fluoro.
