i think that Arce has all the advantages, speed, chin, stamina, skill, they both are about even in power and Darchinyan is a lefty, nothing else, i've seen Darchinyan get manhandled and then pick up a win over a cold older opponant, i just think that Arce will be too overwhelming for Darchinyan, plus Arce's guard isnt too shabby, only punches that go through half the time are straight shots, something that Darchinyan doesn't throw too many of
