Who's the most powerful Heavyweight out there?

[Chase8400]

No contest. Toe to toe now , Vitali would end anyone there.

Haye is awesome, but would lose to almost anybody on that list toe to toe based on his inability to take a hard punch.

Tua is the Roy Jones of the heavies. He is nowhere near the beat he used to be and could not last toe to toe with Klitschko.

[The Hammer]

Vitali Klitschko, without a doubt.

Tye? He couldn't go toe to toe wit Two Gunz man get over it.

[Froch You]

I'd say Vitali
