At 6'0 and 200, in the amateurs you should be considered a boxer not a slugger. I'm 6'1 and I always have to assume the role of the boxer who keeps the 5'8, 5'9 slugger at the end of my punches. Not too many tall guys at heavy in the amateurs. I'm roaming around 185-190 but I'm trying to get to a solid 200.
