Asi Wind's is amazing. It is my favorite, but I know the Berglas effect (the amazing secret) as well. Then there is Matthew Johnson's multiple ACAAN routines, and the Grail GOLD Edition by Mike Rose. There's also Atlas Brooking's The Crusade, and Boris Wild's Birthday CAAN. I would suggest reading some stuff in books as well. I made an ACAAN based off of some moves from Earnest Earick and Scarne, and some mathematical principles, and a easy memorized deck.
