It might have been Vernon who said that there were only a small handful of magicians who can flawlessly do a french glide. I think the point is that a great deal of thought and work must go into the mastery of even the simplest sleights. I think that by and large most of us aquire moves, but never quite master them. We may do them quite passibly, but seldom with the refinement that can be achieved. It may have something to do with the fact that certain sleights are germain to certain effects. We work with the sleight in the context of that effect. Practice time becomes somewhat limited. Therefore, I think that selecting sleights for our arsenal is a tricky affair. The investment should really be worth the effort. Take for example the top palm. With an excellent top palm one can force cards, switch cards, change their appearances, secretly move them to another place. If you select a good technique and master it, the secret movements are indetectable. A mastered palm offers incredible value for the effort. Check the Leipzig book to see how he realized the side steal. He must have done it wonderfully, it was a cornerstone of his card work. So, what's my point in relation to the Curry Move? Whichever method you choose, be sure it offers versitility, a decent angle range, and the potential to be deceptive. Marlo's breakless method really meets these criteria. With some thought you can switch from the center of the deck, switch multiple cards for multiple cards, even switch multiples for a single. You'll get a lot of "bang for your buck." The technique isn't particularly difficult, you'll aquire it in no time. Mastering it? I don't know, I still haven't.
