Hmmm, my post disappeared, or I didn't hit the button...
I'd referred to "both" being okay, depending on your conditioning and time. Lol hit it right on the head too, being that AA's give you better recovery and immediate strength.
I think you have to feel some of this out in relation to your strengths and ignore the pump factor. I can only anecdotally speak from PH usage though, and factually from a couple years of reading. There seems to be both immediate recovery ability and overnight recovery improvement.
