Plugging a hole in my game: Ax suited

[Defendant]

So, for the longest time, I tried playing A3s, A4s etc if I can get a cheap flop, both in limit and in no-limit. Quite a few pros advise you to play them in late position with not much of a raise in front of you (Phil Helmuth for one). Then I realized: In most low to mid-limit games, this is a no-no. Before the flop, you have a 7% chance to hit your flush. 7% means shitty pot odds. So the reason you would want to play this hand is implied odds. Ok so lets say you get the ideal flop, you flop the nut flush. NOONE will pay you off enough to have so high implied odds to make up for the huge deficit you get before the flop. In limit, they might turn into calling stations and call you down, and in no-limit, you cant expect anyone to call a big bet. So lets go through this in a limit situation:

Lets say blinds are 2-4 (since this seems a common limit around here)

You, in the cutoff, Ah 2h.
UTG+2 limps with As 9c. Fold around to you, right now theres 5$ in the pot. Odds to hit the flush by the river are 7%. Your pot odds are 2-5, which is 40%...hi, not good. This means that your implied odds after hitting the flush would have to make up for that difference of 33%, i.e. the money he needs to push in after you hit has to be enough to give you a 7-100 return on your money...dont know about you but thats a LOT of bets to call into a 3-flush on the board.

Now, god forbit an ace hits! Now what do you do?

I honestly dont think A small suited is a profitable hand, because people are too weary of 3 to a flush on the board at low limits (because they get burned a lot by people limping on their Q6 suited CUZ ITS SUITED DURRRR).

This might be different at higher limits, but I still dont think anyone would pay you off enough if you hit.
