I think i would have done anything to the face, not a lot of things hurt more then a smash to the head. Or punch to the neck, not hard, some crack adicts don't feel any pain, but u hit the neck and the throat closes up unableing them to breath. if there drunk or anything go for the knees, chop them down, don't let up for a sec, if you do, they will see the and gain a further advantage. Also try to incorparate elbows, i like to do that because elbows have less smaller bones then a fist, all that punching is sure to injure your fists. peace
