The quick conversion between Si Stebbins and Redford stacks is brilliant. I decided to memorize the
stack, although I already know and use Memorandum. But there are several amazing effects which can
be done even without learning the stack. And the full deck false overhand shuffle has instantly
became one of my favorite tools for the memorized deck work.
There is also an online
appendix with videos, where several effects are presented and taught by Patrick.
