The shootout rules for Aces & Eights doesn't require much in the way of stats. In fact, all you need are two stats (Accuarcy and Speed), hit points and knowing what weapon you are using and how much ammo you have. So you don't need much in the way of a character sheet either. last year I just used index cards for character sheets. This year, I'm going even smaller.
These things will be test-driven at GaryCon V. If they work there, I'll share them with the rest of the internet.
