I have used "fused" lines for several years. I stay away from the braids because they are too limp and therefore difficult to manage. Fireline, Fusion or Power-Pro are all similar products in my opinion. I prefer Power-pro just because it costs less.
I quit using it for drifting though, I think it is too hard on reels and rods. Float fishing would be different though. The lines bouyant quality makes mending easier. I use them now only for downrigging, sturgeon and bottomfishing.
I start the day by peeling several yards of line off my reel to get rid of the frayed and limp line from normal use. This will help minimize twisting around the rod tip every time you reel in. On the other hand, I have never had a spool rot on me and I don't change it nearly as often as mono.

Good luck!
