I wouldn't know who to pick. It's not like Fedor is bigger. This MW vs HW thing is no reason not to do the fight, Fedor is just fatter. That's not functional weight. Lombard is a good sized MW, which is what Fedor would be if he weren't fat.
Stiking I think is even. Grappling edge to Fedor once it's on the mat but doubtful he can get it there. It probably comes down to a kickboxing match and if Lombard comes in good enough shape it should be a close fight.
Can't really think of a much better potential fight out there for him unless I'm forgetting someone obvious.
