I need help choosing line. I've tried a bunch over the years from Berkley including XL, XT, sensation, Maxx, Vanish, and fireline. I'll tell you right now, the Vanish sucks. I've had it a few times on my spinning reels and line easily nicks, and the knot strength is terrible. I will say one thing in favor of Vanish, its very sensitive. maybe others have faired better with it, but I have not. The Maxx has too much memory and is overall OK. The XL is nice and smooth and so is the sensation. I had fireline back when it first came out and really dont remember much about its characteristics. I know flourocarbon is whats popular today and would like to try another brand that might be better overall. If it helps, these are the following rod/reel combos I mostly use and for what presentations I will use them for.
