sounds really brutal. Since I blew most of my left hand away, I had to learn to strike using the heel of my palm. I couldnt make a fist at all.
If I ever hadda defend myself today, Id look around for a two by four or a shotgun. Coure Im a burdgeoning Sumo tyle. (I eschew wing chun for Buflo wing) From watching TV bouts, many of these MMA guys today are just plain nuts.
