I think a good alternate line is to pot the turn. And I think I like a delayed smooth call of his re-raise on the turn. If he's bluffing you let him off the hook too easily when you push.

Besides, the push just screams Ace-flush. i don't think anything less can play it that way most of the time.

Also if he has the K/Q high flush it's easier to get him to put the money in... assuming he won't just automatically do it anyways.
