Blind steal goes bad

[A_K]

Because of the loosness of most of the games where I play, I don't get a lot of practice stealing blinds and playing back at possible resteals. Sometimes I get it right, and sometimes I feel like I'm spewing. So . . . what would you do here?

Villan is 20/9/infinite, but only over about 30 hands. No blind-defense reads, and I haven't seen him do anything out of the ordinary.

Preflop: Hero is CO with T[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/heart.gif[/img].

To agressive? SB and BB were reasonably tight, so I thought this had a decent chance of a successful steal.

Raise here? Just call? Hard to see J high having much showdown value, so even assuming that both of my outs are clean, I am just barely getting odds to peel and see the turn. Fold?

Edited to reflect the fact that it is impossible for me to check raise on the flop.

Edited again -- I shouldn't post when I'm tired. I realize that (a) I have six outs if villan doesn't have a J or a T, and (b) that I'm getting odds even if he has a J or a T. Still not sure what to do though.
