current Wlad vs current Vitaly
I think prime current Wlad would TKO old current Vitaly in 8.
Wlad looks even better against big guys when Vitaly's defense is not that effective against tall opponents, not too mention Vitaly is a lot slower. Wladimir is not going to land as many right hands as he landed on Wach, but he would land some and Vitaly would not be able to take that much punishment. Also, Wlad's 1-2s will hurt him. He probably would suffer 1st career KD and then KO.
