Not WW for pro (one of our WW's at our club is 6 foot 210lbs)...they will dwarf you until the cutting rules come into effect limiting how they can cut and rehydrate. I say LW if you're already at 9% but still, up to you. Have you competed in wrestling/judo/bjj/boxing etc ? If so, what weight worked best for you? This will be a better indicator really.
