PW would win round 6 KO. Berto is a hype job. based on the colloazo berto fight i would say colloazo would put up a better fight. sorry if i'm spelling this guys name wrong....he was a victim of losing close fights to hatton and berto. However in the case of PW at least berto would be a good draw and add a name and belt to PW accomplishments. I was front row at PW vs. Quiantiana 2, so i'm kinda partial to PW. He was a beast that nite.
