Are there any books or DVDs that contain "hardcore mentalism"? Something like guessing names, numbers in new and bizarre ways? Other than billet switches and impression devices, I mean.
I recently seen a Mindfreak episode where Criss Angel guessed a number written on a covered spectator's palm. Are there any other methods to do similar things without buying an ultra-expensive Phonak earplug?

Hardcore mentalism is billet switches, peeks, and good presentation.

Buy Phil Goldstein's book "Prism" a lifetime of hardcore mentalism.

Thank you, Xiqual. I've read numerous reviews about "Prism" and they were wonderful. I'll try to place my order at Penguin as soon as possible.
