We were using 25 and 30lb. Maxima Flourocarbon and some prototype Maxima 30lb. mono that I was testing. I have been really impressed with the two types of prototype mono line that Maxima is working on. The snaps I use are made by a Japanese company called DECOY. They make a few snaps that I use, the V snap and the EGG snap. The one I use on all my hard swimbaits is the EGG SNAP. DECOY makes them in size #3 that is 70lb, #4 - 90lb and #5 that is 120lb. The DECOY snaps have never failed or opened up on me and they are perfectly round on the bottom were they make contact with the eyescrew and do not hamper the action at all.
