Gamboa all the way baby, the thing is Gamboa could conceivably win every round on the way to a KO or it could be a multiple knock down war
At 126, JuanMa probably wins; at 130, Gamboa probably wins. If Gamboa could fight disciplined, he could probably beat JuanMa at either weight, but Gamboa has yet to show that he can actually fight in a disciplined manner.
lopez ko's him at 126 and 130. Lopez's technique is far superior than gamboa's and including the power he has, makes it easy for me to vote Lopez. Would be a hell of a fight while it lasts though
