Wach is decent-ish probably on par with Dimitrenko but has slower hands and a slightly harder punch. He's #4 in the WBC rankings so I think if nothing else it's a move to get Wladimir rated higher by the WBC so he can unify quickly.

The fight I really want to see is Wladimir vs Arreola, because I know Arreola will come to fight....Wlad will still win handily but Arreola will have a go.
