worth chasing?

Table is fairly typical. In the two orbits I've sat at the table, I don't think UTG has folded a single hand yet.

Flop: (3.50 SB) 6[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/spade.gif[/img], 7[img]/images/graemlins/diamond.gif[/img] <font color="blue">(3 players)</font>

I have just barely enough odds to call the double-gutshot in a small pot (I wasn't counting the T as an overcard out).
The downside is that the 5 lets any 9 beat me, and the 9 gives anyone playing JT a bigger straight.

What's your play here?
