If we're concerned about illogicality, mentalism is pretty ilogical too. Why would you tell somebody you're going to read his/her mind? Just get their credit card number and leave, no need for any interaction.
I try to ignore that.
I'm guessing the "Dragon grip" you're referring to is the Jimmy Wilson (JW) grip. On the back of your hand? Great, but hard to recover. For your three fly, you could just sleeve it- not too difficult, and hard to beat as far as cleanliness goes.
To do mentalism, you need to believe it's real. The code of honor is levels apart from the magicians code, because it's NOT just a trick. What you're doing is real. If people ask you how you did that, you can't reply with "it's just a trick." It's REAL.
I think "Slide" from Cultural Exchange 1 is like crazy impossible to perform. It's the hardest move I've seen. Anyone have a good success rate with it? Maybe I"m just doing it wrong?
Hmm. The one in the Noblezada Dvd isn't all that great. (The retention vanish) It's taught a lot better in one of the David Roth tapes, though I don't recall which one.
I love doing Derren Brown's "plerophoria." It requires a stack, but if you add a trick beforehand that allows you to count through the cards and memorize them, you're all set.
First one only, eh?
That'd be Translocation, and it requires a shell.
To perform the entire trick, you need Dean Dill's "Explosion," which costs over a thousand dollars.
Good luck.
I don't have Diplopia myself, but if you need help practicing the script for say a psychological/verbal force, anonymous internet chat sites do the job nicely.
Introduce yourself as a magician, and its just like meeting a person, except there's no fear of failure and you don't need to look for...
