its safe to say helenius ****s harder then vitali

[Alx.]

no, helenius doesnt **** as hard as vitali

[nomadman]

I'd go so far as to say he hits harder than Wlad, but only marginally so. Doesn't mean he'd beat him though.

All assessments of Helenius are based on how good he looked against the remains of Brewster, Peter and Liakhovich.
Helenius is still upcoming, experianced fight fans would give him some more time and see how he does against a fighter that isn't so far past their best days before we would draw comparisons against the Klitschko's.
