I think Diaconu is the bigger fish but it would more than likely have to be overseas & I'd hate Mack to get set back because of home cooking. Its a very winnable fight that Mack could use his speed & his better fundermentals to his advantage.

George is probably the way to go, has some name recognition after the Byrd victory, can be made in the states & is the easier fight imo. I see Mack scoring a KO there!
