I am getting ready to look for my 1st restaurant gig ... I too am coming back after a 4-5 year break and like you, i went through my old material (card college, Art of astonishement). They came out with Card college books with only tricks so those are on my radar soon .... I recently discovered lots of nice effects and some of them i am putting into my restaurant routines
Richard Sanders Aces is a great killer packet trick.
I am waiting on distortion by wayne houchin and Iproject to arrive in the mail this week (hopefully).
Actually, i've been developping a new mentalism effect, where the spectator choses any card (there's no force) and sends me the info just by thought (mind reading) ..... I do not reveal the card just yet but instead i smile , take the deck and say "I can see your card in your mind just fine ...here's what i am going to do, I also know where in the deck your card is, i will send you the number" and i ask them to let me know when they see my number appear in their head .... I then count that many cards down and of course it's their selection.
I just tried it 3 times and all 3 of my co-workers were floored so this is definately going in my restaurant act
