[MA] Best dirty-fighting style for a callous weakling?

[Anthony]

This question is somewhat along the lines of "I made my character deliberately ineffective in unarmed combat, how do I make it effective anyway?" but you might consider Judo. Alternately, just take the 20 points you saved from ST 8 and crank them into raising your unarmed combat skill of choice, an extra 4-5 points of skill is a big deal.
