Bass Pro Shop XPS Flourocarbon, best in my book, never failed me yet. But ask a 100 fishermen and you will get 30 different answers as to which line to use. Personally, tried Invisix, Trilene 100%, Vanish, Vanish Transition, P Line and I think it was Siege but XPS is the best for me by a mile. No memory, very little backlash, haven't broke any fish off. Again just my opinion, but I will say I buy Invisix if I am in a bind and can't get to order my XPS and have it in time. I know where Invisix is sold locally versus none sold locally for XPS.
