JJ in a 4-bet pot, flop line (NL100)?

[Phytopath]

Alright no converter so here goes my manual conversion [img]/images/graemlins/cool.gif[/img]

iPoker skin NL (1$) 8-max
I have been playing my usual tight aggressive style taking down alot of smallish pots.

The villian in this hand is a rock 18/5/3, over about 400 hands and is on the button. Seems relatively weak-tight and makes alot of what appear to be good laydowns. He has about 70$, I cover.

Anyway I am on the BB with J [img]/images/graemlins/spade.gif[/img] J [img]/images/graemlins/club.gif[/img], It is folded around to the villian on the button who makes a standard 4$ raise. I 3-bet to 12$, he then min 4-bets me to 20$, so I call.

Flop comes out

Action is to me, villian has about 50$ left and the pot is around 40$, what is the typical best line here?
