I play sc4 weird .

I use the Claw Method for Tekken, SC is a game that I can't use it in.

I use claw stance to play on a controller as does my boyfriend. I have very small/slim fingers so if I do try to play with my thumb, I can't actually hit two buttons together consistently.

I've honestly never seen this Claw method you people speak of.

This controller requires a claw method of sorts, if it gives you a better idea of what people are doing.
For the XBox360 I could see some advantages, like making slide inputs easier.
I still say that you're handicapping your potential a little bit by not using 2 programmable shoulder buttons.
But then, when using a PS3/XBox360 controller I've only seen button mashing scrub stars use the claw...

I was pretty fond of this controller in my Street Fighter days :)
