arcade stick button arrangement

I been tinkering with diffarent button arrangements to see what feels right for me wile playing super street fighter iv arcade edition on Xbox 360 (i don't mean layout of the buttons, I mean what button is set to what game button, punches kicks etc) I use a 8 button layout (a,b,x,y,r1,r2,l1,l2)

Hoping people will post their arrangements and why they like said arrangement.

Thanks.
