Hi
I got it down after about 5 solid hours of practicing. Not perfect, but performable
And what I did, was performing it to one guy in a room with about 8 people or so, and he freaked out, so the others of course heard that, and kept asking, "what did he do?".
So I told him that he should tell the others what he just saw, and that was amazing, because laymen often do not comprehend what they are seeing, and with a move, or trick, as visual as Shifty, he just went, "I dunno, he just tilted his hand (while gesturing some weird arm motion), and then it was on top!"
That was a nice moment.
I of course showed the others a little later, and they went nuts as well
Go buy this trick!
