Right now I am using 8lb fluorocarbon, and I am having success, but I really don’t like the feel of it as far as casting and sensitivity. It feels like it stretches out and gets weaker when I’m yanking out a snag, etc. I like the fact that the fish can’t see it though.. I’m thinking about switching to a thin braid or maybe one of those superlines??? What about that fireline crystal stuff, it always catches my eye at the store, but I haven’t tried it.
