@Sean_Raf, thanks for the words man, although I'm sure I don't deserve them.
@chrystal baller, I didn't have any mentor ( actually only saw a live magic performance once in my life ), but to let you know, personal instruction is one very good way to learn it and definatly cuts down the time needed to get the pass down , especially if the teacher is experienced in it. Try to get him to teach it or at least demonstrate it to you from various angles ( important ones are: you looking on: front and above, front and below, above the shoulder, direct left and right ). Also, if you have magic friends, do the pass to each other, this is an extremely good way to learn its angles and to point out any flashes on the move. If you have a "test spectator", you could do this on him too ( which is what I did)
Problem with using the pass in ACRs, especially to show a card face up on top, is the amount of heat on the deck, which is why you need to have a good pass to do it. Also, not all passes fit the job ( usually its done by versions of classic passes, more commonly riffle or jiggle , and couple of Hermann versions )
However, you get one of the best effects you can do. In a pass VHS, Ken Krenzel does riffle passes that you'd swear its either camera trick or trick deck. Also, the move has a long history, studying it will make you go through many names in magic, expanding your knowledge and appreciation to the amount of work put in card magic.
Speaking of that VHS, I'll write down a thread soon that talks about the sources I know for learning the pass and post it in product reviews forum. Hope it helps you.
Cheers,
