Hide ko somewhere around the 6th. I say this because Hide has athleticism and punching power in abundance. He also picks his punches well. Maccarinelli has a poor defence, and can be found easily and overwhelmed (see the Haye fight).
Enzo by early knockout. Hide is way overrated, same with his power, plus he is getting old...Enzo will blast him...
They both fight as Cruiserweights now. And both are very good. Its tough tell who would knock out who?
