I use fireline exclusively on my spinning reels for throwing tubes, jigs, and spoons. I do not use fireline for throwing jerkbaits. I have not tried it on my baitcasters. I love the stuff. I do use a flourocarbon or clear line leader. I also use it in St. Clair lake for smallies and it works as good as any other line. You get so much more distance per cast, and NO Memory.
