If he moves up to WW, he would beat Pac's record. If Nonito dominated lower weights, I think he should try the same path as Pacquiao, because even if the risk is so high at the higher, especially at WW, there are lot of money circling.
Donaire can beat everyone in BW and SBW. I think later he will move up to FW and challenge Gamboa and Lopez. Well he can move up up to LW and compete there.
