What do you want to know? I think the weight categories only apply if you're going into competitions (like the ABA's or the novices). Most of the one off shows I've been to the fighters just have to be 2kg within each other. 3 x 2 minutes rounds..Is it 4 if you're in competitions? I havn't had my first bout yet so i'm not 100%. Maybe someone who competes can shed more light. The gloves they've used at every show have been 14oz as well. I always thought amateurs was 12oz.
