How to play a combo draw?

[Black winter day]

Example from NL200: I had 6h7h at the bb, mp raised to 7, button and Sb called, i called as well.

Flop is 4h7c10h.SB checks.
Do i c/r the preflop raiser?
The pluses here is that you can often win a pot right there, along with the dead money.
The minus is that you commiting yourself to the pot and if he (or someone else) happened to flop a set, that's bad.
The check part is good also because it allows us to see the action, if the raises cbs and gets reraised, i think i can fold this...

Lead out?
This disquises our hand, but we are opening ourself for reraise and may-be will not have the pot odds to continue (unless, we push back by ourselves)

Just check-call?

Are you willing to go broke with this type of hand if all the other players except the preflop raiser fold?
Basically, i am only a big underdog to a set here and have great folding equity vs an overpair (and practically even money if we get it in there).
