I think the biggest issue with playing AA post flop is the amount of times you come up against aggression like a c/r or reraise and don't think you are beat. You are clearly beat unless you are playing a maniac. Most players will only make a move like this with the goods. If they only had TPTK they would flat call your bets most of the time.

If you get it all in ahead with AA and get sucked out there is nothing you can do.
