i learned the pass and riffle pass from the same spot luis did its a dvd by brad christian from ellusionist titled ninja 1, the only problem is brad has to rush through it on bits so you have to go back and watch it a few times, my pass isn't good enough to fool a blind horse, but thats because i havent practiced it enough, brad christian shows you exactly how to do it and make it invisible even if theyre staring at the deck, shows you exactly the way he does it, and his is flawless, i also like his because of his riffle pass, when he does it with an upside down card it looks as if the card really changes on the riffle as if it bounces through the deck, i was watching a bunch of people try it on youtube, and theyre pass was flawless, but the riffle was late and it didnt look the same, brad shows you how he does it and makes it look amazing
