I'd put Liu Siu-Jian last, since he struggled most with his opponents. Then I'd put Mad Dog above Martin since that guy was just nuts. Taking on 2 skilled opponents like that, one of them having enough skill to take on a full corridor of enemies.

Mad Dog would have beaten them to death if they hadn't gotten lucky with that light bulb.
