Recently I've been using a modified OHTP a friend of mine showed me, that gives you almost instantaneous clean-up, but the only problem with the top palm in general that I have is that you cannot curl your first finger unless you have very large hands. The Clipshift lets you hold the deck like you would during normal biddle/end grip.
I have to agree with everybody, it was a good performance, but try to cut down on the bending and shaking of the deck. It makes it looks fishy. If you watch Dan and Davie (yes I said Davie) or Chad do it, you can see they only shake the deck as the move actually happens.
