What is my flop play?

[mongidig]

Great game. It is loose and aggressive with a couple semi maniacs, and the rest just loose and dumb.

I raise UTG with AdKs, and get six callers including the blinds. I have the image of someone who is definately not weak tight.

The flop: Js7s3c

SB checks(He is one of the semi maniacs. He loves to check raise the flop with any kind of draw including just overcards and then check the turn when he misses), BB bets(He is loose and very straightforward. He at least has a Jack here. He does become passive in the face of aggression). I am next....What should I do?

Please no preflop advice.
