I feel similarly. This move doesn't really fit my performance style, I try to refrain from appearing to flourishy. However I think the idea is really, really neat. And it really does allow you to manipulate the card however you please. Depending on where you apply the pressure and how you align the card, you can get it to go just about anywhere. I also was actually playing with a routine using a laser pointer, claiming that the laser pointer affected gravity, shining it on their card for a while, then having them point the laser at the spring, and their card jumps out at them. It was pretty great, It just doesn't fit at all with the other things I perform haha.
