Thanks, actually I've already ordered 4 Skin Feel grips. I'll test them side by side with the leather grips. A friend of mine has the PS GT and I've actually felt that the Bab SF really stands out the bevels, so it should be a good option too.
I'm waiting for my Gamma Dermagrips to arrive, they should fit me well. I'm currently using Wilson Profile and it's a bit thick.
As for the weight, I'm also planning to use 1/2 inch wide Gamma lead tape under the replacement grip, if the leather really doesn't work for me.
