Cotto vs Vernon Forrest? If they fought ,who would you pick

[Fox McCloud]

Why would a fighter move up to take a fight like Vernon Forrest when he doesn't have to do almost anything to make 147? Especially since the talent at 147 GREATLY eclipses the talent at 154. Seems like an awful career move to me. It probably depends on what weight it was at, and I don't see either fighter moving to the other's weight class.
