I feel that with a big stack and the kind of opponents I'm dealing with at the $5.50s that the reraise preflop is okay. Normally I have no interest in AJs this early, but I chose to get involved here. Is this a mistake?

On the flop, I feel the push in unexploitable with all of my outs if he has actually hit. Correct?
