Hmm. This is actually fairly tough. On the one hand, bug/psychic, we have a quirky typing with common STAB attacks that get fairly decent neutral coverage, but only one notable SE Hit (fighting, which it gets a 4x resist.) and has a hard time coming in on anything. On the other hand, bug/dragon, we have one of the worst dragon-typings possible, but it's still a dragon. (But he was still trogdor) and dragons in OU are a mixed bag. Everyone prepares for one, and every team has at least one. That there is a risk, but is it enough to offset the fact that it has an easier time coming in on things?
Actually, I don't think so. bug/psychic would work better. PLUS the typing alone has a bit of inherent reward, as a certain spore user is getting major offense boost, and bug/psychic is uniquely tailored to shut it out. It gets my vote.
