Does he felt them post-flop with overs? If so, this is a very good reason to re-raise him PF. Yeah, he'll hit his set sometimes in these situations, but you'll win your share.

Also, if he gets passive post-flop and just calls if he doesn't hit a set, but raises with a set, he'll be easy to play against. And if he folds to overs when he doesn't hit a set, you've got a great opponent to play against in position.
