honestly, I usually go for the heavier fighter, but I gotta go with the old addage: you can't beat what you can't touch. I don't think that Cotto is fast enough to deal with pacman. However, if pac is going up in weight, the added weight might slow him down...I need to see some pre fight footage of them training to determine this. I mean, if all things were equal, pac would win cuz he's just faster and he has KO power...BUUUUUT, weight gains can affect fighters adversely. I'm still gonna go pac for now. I need to see some pre fight footage at least a week in advance though.
