OMG I can't believe you people are having so much troubles learning this move!
PM With any questions you have, this move is really easy if you do it right.
Pretty much any move is easy when it's done right, so kudos to you for being able to get the Clip Shift working for you, in however many days/weeks it took you. But I have kept practicing and have improved the Clip phase so far, now I'm sort of stuck on the Shift phase. I know I'll get this move down eventually, and since I love practicing, I'll continue to work hard on it, and it has actually been a somewhat fun (and irritating at times) utility card sleight to learn. I feel the same way Dai Vernon did when he was explaining difficult sleights/effects etc on his Revelations DVD set. It is so much more rewarding once you learn a difficult sleight that many others gave up on. And if you don't like practicing or only look for self working tricks, or some trick that says, "You'll be performing this effect by the end of the day!", then maybe Magic isn't right for you.
Now I am not saying this about ANYONE on this form or this thread, it's just great insight to becoming a confident Magician.
Anyways, since my right hand no longer aches, I think I'll go back to practicing
