Id like to offer three suggestions.
First, it's always a bad trade-off to sacrifice long term, permanent benefits for some short-term, temporary payoff and that sometimes happens with people starting out in memorized deck magic.
Given that, once memorized, you plan on using your stack for a long time, and you intend to carry that stacked deck around with you often, its only sensible that your stack ought to have as many features and benefits and flexibility built into it as possible (consistent with still keeping its random appearance).
It is simply short-sighted to sacrifice such benefits by choosing a stack that might be slightly easier to initially learn (because it was intentionally structured to incorporate some helpful guideline, rule or formula) as opposed to a stack that was structured to contain the most magical impact.
Second, it can be tempting to include a zillion neat features into your stack, but they often wind up being of theoretical use only. The key question is: which features will you really use, in your own practical performances? If some component feature is something youll really do frequently, or even only occasionally, then thats a plus. But Ive seen a number of stacks which theoretically can do something (e.g, transform into new deck order, or red-black order, or stay-stack, etc) but in practice they would be rarely (or maybe never) used. Why? Sometimes because the necessary procedures to get there are cumbersome or un-wieldy: extensive shuffling runs, or too many faros, or multiple rounds of dealing in practice they deaden the pace, and lose the build up of excitement that the preceding memorized deck effects have already created. Or sometimes the feature is only theoretical because one hasnt fully thought through what youll do once you get there, or what prior effects have preceded it, or where in the routine it will come. If your memorized deck routines build, with each effect being successively stronger, then some other effect (based on a built-in feature) may not be able to follow it, purely from a presentational perspective. And then, of course, theres the trade off the more extensive a feature is (especially full deck features) the harder it is to also include other useful features. So, my suggestion: look at your own personal performances: how long your sets are, what procedures youre willing to go through, what specific kinds of effects you like to perform and then pick a stack that gives you something that you will actually use.
Third, theres way too much emphasis on being concerned over how difficult or easy it is to memorize a stack. People worry, and chat about, and research how to best memorize something and all the time, theyre not doing it. The short, candid answer is, practically all stacks will take about the same time to learn proficiently, i.e., well enough to use in practice. Even when theres a minor short term benefit of a rule, guideline or formula, it only matters during the initial few days of learning, because after that youre going to be relying on your own real, instantaneous recall (i.e., direct memory, without a crutch of any formula, rule, mnemonic image, or the like).
I dont know of many people who have seriously made a concerted effort to memorize a deck but still couldnt do it. The only people who talk extensively about the difficulty of memorizing a deck are the ones who are postponing trying. And its a red herring to worry about HOW to memorize it. Juans methods, or the mnemonic systems outlined in my books, or straight rote memory all work and theyre not mutually exclusive. You can start using one method and, if it doesnt work well for you, you can switch over to another method for the same stack, without any confusion or backsliding. You can combine these approaches you might wind up having memorized some cards because of theyre visual mnemonic images, and other cards because of their sing-song tunes or visual colors a la Juan, and other cards simply because they stuck in your memory from the start. The end result will be the same and completely usable: youll have memorized all 52 cards. So, go out there and do it.
And, while I dont want to plug my own stuff too much, I think theres lot of information and illustrations on Volume 3 of my new DVD set that will help you think about and answer many of the issues raised in this post. And you can download for free my Introduction to Memorized Deck magic Memories Are Made of This all at www.simonaronson.com.
All of this information is totally independent of which particular stack you ultimately choose.
