Hazmat, you're the shorter guy, right? Like tito said, hit em as hard as you want. The TRUTH is, you suck. (someone's gotta tell ya. we all do at first. ) The key is to go in with better guys who will know how to handle your full-out efforts. You can swing for the fences...the better they are, the less you'lll hit them (especially when they really try to avoid getting hit) That's why trainers put newbs in with experienced guys...so someone's in charge at all times, even if you think it's you, when it really aint.
