Med PP to a turn overcard

I'm still gettin the 6-max feel down. No real reads except everyone has a 40+vpip.

Preflop: Hero is Button with T[img]/images/graemlins/heart.gif[/img], T[img]/images/graemlins/spade.gif[/img].
<font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises</font>, SB calls, BB calls.

Flop: (6 SB) 4[img]/images/graemlins/heart.gif[/img], 6[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>

Ok I called the flop donk-bet - I figure villian could have a flush draw, wacky str8 draw or maybe the flop barely grazed him (pair of 6s). In retrospect I think this might be worth a raise? If I am re-raised I can call &amp; fold to a turn bet UI (don't pick up a flush draw). My rational for the call is that if he's betting with a 6, 77, 88, 99 I want him to keep on bettin and a raise would have slow him down.

Oye, another overcard. I called hoping for another heart on the turn.

Final Pot: 7.50 BB

Am I right enough to make this call profitable? I saw too many ways to be behind in this hand to make this showdown profitable. What should be my line throughout the entire hand? For some reason call call fold just seems wrong.
