Amazing what a difference the strings make.
I used to use D'Addario .11 sets too, which I still like alot. I've switched to Feline Legs 11s though, I got a nice deal on a box of them, and I think they feel that little bit nicer.
Once I had to use Rotosound 11s, which many people dont like, although I thought were the best of the bunch - the thing is though they broke extremely easily... I won't be fitting them again. Not keen on Ernie Ball either, for different reasons.
I play with a pretty heavy right hand I suppose so, not having the strings break is important to me.
