I use a lot of Trilene XL, more so than any other type.
You and me both. But, I really like the chameleon colored 3# Maxima if I can find it for a good balance between 2# and 4#.
I spooled up a bunch of different reels 2 years ago with different brands of Flurocarbon. Of all the choices out there, for my usage I'm leaning towards Vanish. P-Line has too much memory, and there was one that really seemed to twist badly no matter what I did to untwist it, and no matter what lure I used.
