I liked his "which hand" effect, I believe he calls it "Lies" here, but I will never use it again since he improved upon it about 1,000% with his Tequila Hustler principle for divining which hand. It comes down to process: the CAM way is actually a little easier--though not much--but is wholly inferior to Tequila Hustler. That process removes the appearance problem inherent in all the other routines using the same principles. (I think they all got their start with Banachek's brilliant "Ring of Truth," which I use even if he doesn't anymore. It's great.)
