i know there is endless debate about rocking your hands when doing a pass. In the case of this video it is def too much. If you are doing the pass on an off beat, the hands seperated and while talking, then casually bringing the hands together, it is fine to not rock as no one will be looking at your hands.
However, if you want people to be able to burn your hands and make the pass a "move" such as a color change or in an ACR, having a face up card pop up like jonathan kamm's, a slight rock is crucial to cover the two spots where the pass can flash: the back left corner and the replacement of the packet to the bottom.
Kamm, akira fuji (best pass ive seen) and jay sankey all utilize a small hand rock.
Not to in any way compare my pass to theirs, but check my video:

I can promise that I use this and call attention to it and no one questions the rock as long as it is gentle and done at the wrists and not with the whole body moving.
Of course, if i am performing for more than a couple people, where angles get to be a problem, i will not do this as a move, but instead on the off beat as mentioned (or use a different control all together)
It may not be the best way to handle an audience, but I really enjoy getting moves by people while they burn the hands. I sometimes wait to do a top change while gesturing rather than when making eye contact, as it makes the effect that much more awe inspiring.
