I'll mention two great effects that will be coming out soon, both packaged together, both Larry Becker effects, "Perplexing ESP Plaques", and "Sneaky Two" they come in both close-up and jumbo the selling price will be $20.00 and $40.00 BTW the JUMBO plaques are limited to 100 and then they will not be made for another 5 or more years. Murphy's has all 100. At any rate you are aware of the "Sneaky Two" effect it is a version of "Sneak Thief" Perplexing Plaques allows for many of the same type effects and as you said these are nice effects because you are putting objects into the hands of the spectators which does tend to keep them interested a little longer. We thought combining these effects with the same plaques/clip boards would be nice as you can do multiple effects with the same props, as opposed to pulling out one set of clip boards for one effect then a second set for a different effect (that would be like using a red back Svengali and a blue back stripper - not only would it help you in knowing which deck does what but it would also tell the audience you have a different deck for a reason)
You sound like you have a lot of experience and know what will and what won't work for you. I suggest you consider whether the perplexing plaques, would work for you, one nice thing that many people don't think of when using these is that they are like a board game, you get five plaques (meaning you could use up to five people) most people think you have to have five. Obviously for some effects you'll need all five plaques, but some effects you'll may only use three or four, for "Sneaky Two" you'll only use four. The flexibility of these props help to make everything appear to be even more on the up and up. if you write me privately I will try to explain it better, but these boards with Larry's routine's and ideas can make anyone look great and we left the marking/coding system up to the end user. We give several suggestions and supply the material to mark them the way you want... so in the end your set can be different from everyone elses, helping performers keep their individual styles. As I said before, Murphys has all 100 of the Limited Edition Jumbo Plaques, if you are interested in them or the close up version you might want to contact either www.elmwoodmagic.com
or your favorite online dealer and ask them to try to get you a set, when you get yours contact me with me with any suggestions or questions and I will help you as much as I can, giving you further suggestions. I played with these for a very short time, but can see the value of them for a good performer and someone that is creative can take, Larrys ideas, Dan Tongs ideas, and my ideas and have a blast twisting them into total miracles using design duplication, mind reading effects, you name it the spectator could go through the five plaques one at a time, then concentrate on just one of them, the rest could be put back into their envelope or dropped into your pocket, and you would instantly be able to tell the spectator which plaque they were/are concentrating on. This really is one of the props that are only limited by your imagination and I think anyone that buys them will enjoy them as usual we kept the price low, and give away tons of extra options, and information.
These things really are a lot of fun
