I thought about the new guys for a while but I have to say that a couple of now-long-gone members take the cake for me. Wyllius vs. Nait for world domination is just too irresistable.

EDIT: Of the current lot, though... ShlupQuack vs. Leeza, for some feisty action. And it wouldn't be any catfight, either - those two would have a battle much better than some WWE Divas attempt at a fight.
