AJ 3bet, raised on flop by loose villain

[PinkMartini]

I'd call and expect something like KT.

[Asheh]

easy call, he has A4

Even loose idiots get good hands and make a normal preflop raise with them. Will he really overcommit with any ace here?
I need to know he's raising any ace preflop (19% prf is not likely to contain ANY ace) if he's positionally aware (that would make it more likely he is raising weak aces preflop) and if he likes to bluff big.

It's very marginal and a very big bet... I think I still call, but it's definately not an easy call even against a total retard.
