FD + bottom pair - flop line

[student_of_game]

400NL. Villain has ~$320; I cover. I haven't been at table long, so no strong reads. I haven't done anything out of line, and I don't think villain has at this point either.

Villain min raises UTG. Button and small blind both call, and I call in the BB with K[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/heart.gif[/img].

Flop (4 players, $32): J[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/heart.gif[/img]
Checked to me, and I lead for $20. Villain pops to $80.

I... ?

What do you think of the flop lead? Should I c/r or c/c?
