Standard AA EP. Best Line?

[Mercman572]

Hero is UTG+1. MP1 +MP2 are loose, but no reads other than that.

Paradise $.5 BB, villains have a full buy in and I cover.

raise 2.5, MP1 raises 5.5, MP2 calls, folded back to me.
Hero?

I thought about making 15 to go, but felt that it would scream AA, either villain could call with a lower PP and dump a missed flop, plus I don't know where I'm at being OOP the whole time if villain raises. Cold calling seemed absurd. I figured given the action one of them really likes there cards and pushed, deciding I'd be satisfied with the $14 i'd get from a fold, and I'd charge worse hands the maximum to try and outflop me.

Whats the best play here?
