What do you guys think about checking when you hold the probable best hand?

Early position, raised with JJ, got re-raised, so I just called (I was big stacked at this point; had the other guy 2 to 1).

Flop: AAJ

Do you check that or bet it? (Note: I am not worried about AA or AJ; I'll pay those off.)

The reason I ask is that I try to avoid developing a pattern of betting weak and checking strong hands...but it seems like I'll probably get a fold if I bet anything at that flop.
