My favourite tabled false shuffle is a bridged push-through (which is different from a pull-through apparently, although explanations seem to vary on what the difference is). I got that variation from Richard Turner's The Cheat DVD, but the basic push-through is taught on pretty much every gambling technique DVD and in almost all the standard books. It's not taught in Erdnase, although he mentions it in passing. I'd recommend that you learn the push-through and an up-the-ladder cut. When done smoothly, it looks almost impossible that you could retain the order of the deck as the audience gets a clear image of cards being shuffled into each other, then the top card being buried under successive cuts. Also, it looks a little bit flashy, but not too much, as if you know how to handle cards, but not as if you're controlling them, in the same way a professional casino dealer might do. For gambling demos, therefore, I think it's perfect.
