I just put a set of the Fusion Nickel Wound on my Super Strat yesterday (first time user) and am impressed. They are warmer than most other nickel wound and just have a good feel to them. I'm a convert!I met Curt at NAMM yesterday. He gave me a couple sets to try and I just finished putting a set of Fusion 11's on my personal guitar an hour ago. As a player, I was sold within the first few minutes. They seemed a bit stiffer than the D'Addario I've been using for the last few years and in a positive way. I'm planning on going back to talk to him this morning and if I like some of the answers, I'll start using them on all of our new guitars immediately.
