I like the call alot more if there's a flush draw on the flop you can bluff at later on the turn and river. Then you have your bluffing outs when the flush card falls and you real backdoor flush and gutshot outs.

This of course presumes that villian would lay down to heavy action from you if you represent a flush you don't have.

Without any bluffing equity later in the hand, I think you try to peel off the jack on the turn and then bail when it doesn't come.
