I think a lot of folks mistake the confidence with which they fish something for it actually being better. There's a lot of placebo effects in fishing, and I think fluorocarbon trout tippet falls in that category. If it works for you, I'd keep using it. But I've compared them side by side on many occasions and seen no real difference in catch rates (certainly nothing that justifies the 50-75% price premium), and fluorocarbon by its very nature has some properties I'm not fond of that are particularly noticeable in small diameters.I've been a big fan of Seaguar for a long time and have been buying big spools for any of the larger diameter stuff (8+ lb). I've recently added trouthunter in the smaller sizes because because I like the spools so darn much.
Obviously you're welcome to your opinion, but my experience doesn't match up with this in the slightest. Other than needing a good drift, no matter what you're using. That is definitely underrated/not understood well enough by a lot of folks.
Now in saltwater, where you're jamming thick ass hooks into hard ass mouths; for gear applications that benefit from minimal stretch; and for fishing really deep with conventional tackle, fluorocarbon is fucking king.
