From what I recall, I believe AA6 is the only POS you can do.
However, theres 33AB4...it's pretty solid as it tracks and you can hit confirm into B...or you can 4 POS going backwards even DURING the animation of B.
Wow, hit confirming? Awesome. But I swear that AA had a 4 as well, with one being into full crouch. Huh.
