I use 14#XT green. I have tried the fluorocarbons, but have a tangling problem with them. I tie my harnesses in the off season and store them in 3" X 3" zip lock baggies. With the Trilene 14# XT I can take a harness (3 hook, 8 bead) out of one of the bags, hook it on and I'm done. With the fluorocarbon line when I take them out to use them, they invariably tangle and I spend a couple minutes before I am fishing. Small thing, but it gets annoying.
