a super six would be nuts. steve, marco, and krystof are all well conditioned fighters who fight their own particular style well. they can all hit and get hit. id pay to see any of these three guys fight each other. when steve and marco fought... it looked like war for 12 rds. krystof is a little slow but he can go 12 rds, take a beating, and when he does hit, then its a solid punch for sure.
