Personally I like the present heavyweights because you never know what is going to happen.I like watching Wladimir and Vitali KO their opponents.I like the power and size these guys have compared to the smaller lighter fighters of the past.I really didn't care for Ali's style of fighting, to much shoe shinning and not enough mixing it up and knocking out opponents.Wladimir has excellent skills and they are overlooked because of his size, sure he has tons of power but he always outboxes whoever he fights.That is the kind of fighter that is exciting to watch.
