I've been playing around with my grips too (75 Shadow), choosing from among the factory rubber grips, the thin aluminum grips, and the thin very checkered (lemon grater) grips. Interestingly, I'm getting best results with a rubber grip on the right side and the lemon grater grip on the left side (I'm right handed). Its nice to have a few choices so you can mix and match to find the best combination for your hand size and shooting style.
