[Shattered]

I agree, raising flop makes this a lot easier to play and is good simply for value as well.
As played you're afraid of pretty much just a six, although occasionally he shows up with something really [img]/images/graemlins/confused.gif[/img] like aces (you didn't specify how or what kind of bad he was). Even with the overbet he'll be valuebetting worse or doing retarded bluffs more than enough to make the call worth it.
