I'm about to memorize a full stack. Darwin Ortiz's Scams & Fantasies with Cards
series is what pushed me to try one.
I believe I've got it narrowed down to three options: Tamariz, Aronson, and whichever stack Ortiz is using in the DVDs. (I get the impression it's a stay-stack, which is easy to get to from the Tamariz stack) Although these three are the front runners right now, I'm definitely open to suggestions.
I have a few big priorities for the stack:
1) It's not an algorithmic or cyclical deck. I want to have a reference list in my head of number X to card Y and vice versa.
2) It is easy to setup from new-deck order, even in front of an audience. (I can do a perfect faro shuffle)
3) It has a number of good built-in effects.
4) It looks random when spread face up.
Right now I'm leaning towards the Tamariz, mainly because I've flipped through my copy of Mnemonica and I like what I've seen. I haven't done enough research on the Aronson deck or any other deck out there though, so I'd like to hear about them some more.
I don't mind buying another book if I like that stack better, so promote your favorite stack here.
