I usually throw medium driving crankbaits on 10 pound red label flouro. If I don't retie, eventually I will rip off a cast and my crankbait will be sent to the moon. Flouro is great but it does not like  to be stressed like WTM is says. It gets stressed from casting too. With a crankbait I am looking for maximum distance and giving it  all I got on casts. It is not if its gonna snap the line but when its gonna snap.
