Arce would beat Darchinyan.He would nullify his power by going to the body,throwing tremendous amounts of power punches. Darchinyan has yet to fight anyone near the calibre of Arce and he relies on 2 things,his power(which IS awesome) and he thinks he can walk through anyone.I think his defence is too leaky. Also,I'd love to see Viloria against Vic,I think Viloria could outbox him.
