This is of course impossible to answer as we dont no what Doniare will look like at the higher weight. But assuming he carries the weight well, I'll choose Nonito. As Gamboa flys in with his attacks, Nonito will be fast enough to counter him. For the first time in his career, Gomboa will be in with someone faster than him, and who arguably hits just as hard. I see a back and forwords battle with Donaire knocking his man out late. Doniare TKO 10ish
gamboa should destroy him in 5 rds. i don't see this fight happening by the time nonito fights at 126, gamboa will probably be 130 or 135. there have been talks about rios-gamboa fight down the line.. should take that one into consideration. we'll probably see donaire fight john or johnny gonzalez.
I don't think Nonito could K.O Gamboa .... at 126 Nonito would lose of his speed and besides that Gamboa has more power,hardness and agility in the ring than Nonito ..... this is one type of the fight that it must happen.
As of right now not seeing how Donaire looks a the new weight,i go with Gamboa. IMO Gamboa is the faster fighter out of the two for the record.
