Straight flush draw too aggressive?

"grunch"

I see no reason to raise on the turn. You still only have top pair/worse kicker. With one card to come you're approx. 5-1 to make the flush and you're not gonna get anywhere near the pot odds for that with a raise, plus the risk of the reraise. While villian is aggressive, he's also tight so he probably has something. I'd go to the showdown but until I hit the flush, I would go as cheap as possible with the 2 kicker.
