Have been using Berkley Vanish flouro on my spinning reel for shakey head for the past three years and i love it.
Need to respool often because of line memory, fish it around rocks alot and should retie if you feel any nicks, very strong line, i use ten lb test and virtually invisible under water. Have tried it as a leader on my braid and broke off alot so now I just color my braid with a black marker seems to work well. Also does not stretch so you dont need to jerk real hard on hookset.
