Most recoil pads are OK. I'd try to stay away from the "diamond-sided" and white liner variety.
Rowdy Yates turned me on to "Limb-saver Recoil Pads". I'm sold on them! They have a 'grind-to-fit' that will work with almost any style gun (comes in sm med & large, so check dimensions first).
I've fitted 5 of these so far and I recommend them for anyone.
