I reckon light weight. He doesn't look too heavy!! I bet hes quick and pretty strong with the punches. I'm not sure how he would handle himself if he got hit tho. You have to be pretty controlled to deal with hits. I got hit in the head in my last taekwondo tournament and i just ignored it. You can't afford to sacrifice the rest of the round just because you got hit. I'm not sure if he could do that.
