Dan,
As one who had great difficulty with Chubby Checker's Twist many moons ago, I sincerely hope Lee's move is less energetic!
More seriously, assuming we knew how to do the Asher Twist (which I don't) nobody here would dream of giving away such information. Lee Asher covers all this very neatly as it's his effect and he's the only one who can legitimately provide the details - for a fee. As this effect costs a mere $15 plus P&P I'd say that would be a fairly low-cost investment. However, if you look at Lee's website, you'll see the encouraging words
'Ricochet' is a variation of Paul Harris' very popular trick 'Reset.' Paul Wilson offers two different handlings. One handling requires the Asher Twist. The second handling is sleight free. Curiously, both handlings play equally well for a lay audience. This means that regardless of your skill level you can perform this very strong piece of magic. In addition, the clean up is very simple and very deceptive. The spectators have eight genuine cards.......
so there's a version which doesn't need the Twist as well.
Why not add it to your Christmas wish list?
Of course, all the above assumes you haven't bought the trick but if you have bought it and still have problems (and we all know that feeling, don't we children!) why not e-mail Lee and make a strong but polite request for additional information? You never know, he might just help! Best of luck!
