after reading the responses thus far, I noticed that snakehead was the only one who advocated raising. Far be it for me to advise you contra to snakehead's thinking, but I don't think a raise is that great here unless you truly have a hand that you want to build a pot with.

You don't want to get a reputation of someone who'll three bet then muck on the flop in this game. Keep the party going. If it's going to be capped anyway and you have a hand you want to play in a capped pot in this game, why not just go with the flow and let them do the dirty work.
Note that this is purely an image type play. you don't care that they put you on a hand or not, since it's highly likely that they don't care what hand you have. They will notice the guy who raises then mucks on the next street, though. They'll see you as the party pooper if you do this. If you call then muck, though, you're just another party goer who bowed out early, and the revelry is more likely to carry on.
