Agreed you probably got the most out of him you could 80% of the time, but I would try to induce a bluff here. One question, why do you think BB lead out with 30 on flop? Even a paired Jack would make a bigger stab than 30?Typically when I see this play the initial bettor is begging to get a raise and then check raises to take down the pot. This works well when you have the set and also works well as a bluff (especially with a flush draw)? I think you raise him here and you just may get some action, or you can just call and sneak out another 60 or 90 chips? To me just calling screams "I am not afraid of the flush".
