Top set facing possible river scare card, how to play?

I prefer to block; pretty opponent dependent though.. Against a very LAG player, I probably c/c this, against a nit, block-bet is the way to go IMO... with no reads, I feel like you could make a case for any of these..

Isn't a block bet only good if there are some 2nd nut hands out there that will call a block bet but bet bigger if we check? Here we are only worried about JTxx which is obviously raising a block bet. If he's a calling station I like valuebetting here. If I'm betting $30 I'm probably not folding to a raise due to stacks being so swallow.
