i have mixed emotions on flourcarbon after reading some posts here kevin. i saw where wally world is now stocking 100% flourcarbon. forget the brand though. is this a better flour?
If you're refering to "Berkley Trilene's 100% Fluorocarbon", then I'll give you my honest opinion... it's sub par. I really like Bass Pro Shop's XPS Fluorocarbon. It's reliable and much more manageable than Trilene's 100% Fluorocarbon.
As to my opinion on fluorocarbon lines in general... I think fluorocarbon is the best thing since sliced bread. I throw fluorocarbon more than any other type of fishing line, and only use mono for baits where I need buoyancy, like topwaters and spinnerbaits, and any other "specialty" presentations that require a lot of stretch or bouyancy.
The first generations of fluorocarbons left a lot to be desired, but good fluoro's like BPS's XPS have come a long way, and if treated right, don't give you much problem.
Fluorocarbon gives you a lot of advantages over mono... less stretch, less visible to fish, more abraision-resistant, line sinks, lasts longer, doesn't weaken overnight, and more. I'll put up with a slightly less pliable line to gain these advantages.
