Am I giving $$ away?

I'm not sure how I feel about my line in this hand, it felt right at the time, UTG(500) had previously min. bet a couple of hands where he had top pair on every street.

5/10NL I'm in BB (1300) with 7 [img]/images/graemlins/club.gif[/img]2 [img]/images/graemlins/club.gif[/img]

UTG limps (sees a lot of flops) SB completes, I check

Flop is J [img]/images/graemlins/club.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/spade.gif[/img]
check, check, UTG bets 30, SB folds, I call

- My thinking here is that, he probably doesn't have top pair given his previous actions, and I may be able to move him off any scare card, also I'm almost definitely drawing live

I lead out for 60, UTG thinks and calls

- Following plan, was a bit disturbed when he cold-called but I think a draw is more likely than a made hand

I lead out for 200...

I just didn't feel like my opponent had a flush here, but I don't know about this line...seems like I'm going out on a limb..comments?
