The pass is the only sleight that I have ever learnt from a DVD! I wouldn't usually recommend much Ellusionist stuff, but I think that ninja 1 was a really good intro to the pass. Then I supplemented that with EatCT and Darwin Ortiz's stuff.
The only two passes that I use now are the riffle pass (as a control and a colour change) and a pass I developed independently (which uses a gambler's cop type grip) which I can do almost surrounded.
