Yeah well in your version your covering hand moves forward making the whole effect hugely obvious. I prefer the way its taught in the book, which is strangely consistent with the way its taught on the one on one. You did it wrong, and it didn't look as good as it could as a result, because moving your hand forward and back just reveals the effect, when you could instead just be moving your hand back, making the effect look utterly impossible.
If you're OK with that, then fine, but your video was no where near as awesome as the feedback would suggest here.
It was good though, lol, just not amazing.....
