A ton of outs and players, raise turn for value?

[teajay]

I've got no reads on anyone at the table, second orbit and haven't seen anything exciting. A few more people seeing this flop than average though.

I'm figuring that my J outs are mostly clean, the J[img]/images/graemlins/heart.gif[/img] slightly dirty. So, 3.5 outs for the straight. Maybe half an out for the 10? and the 9 outs for a flush. So about 13 outs. If there were a couple callers behind me already I would certainly raise this and trap them all for one more bet, but in this case should I call and pad this pot?
