I agree that you won't really know what you like until you try different grip styles.

To clarify, I have shot a lot of different ones, and have pretty well decided what works for me/what I like. Some grips, to me, are completely uncomfortable and require me to fiddle with hand placement to get it "right". You'll see on some message board where folks will tell you that you have to do this or that to shoot a certain style grip--that's not for me. I want my grip to fit when I pick it up. A little large or a little small isn't a big deal--uncomfortable (or in some cases a bit painful) is something I just don't care to shoot.
