I thought I recalled him motioning them to his shoulder or wrist, but that was just him motioning for a new uke. Either way, it doesn't really change anything. I get that it's a demo and the point isn't for them to flatten him, but it's hard to ooh and aah over it when you know it's a by the numbers demo that has been done so many times and with such consistency in what uke gives that it is for all intents and purposes, rehearsed. Even with all that, there are times when he kind of loses uke, but since he's done this a thousand times and there is no resistance, he just keeps ticking along. I wonder if he gets bored doing these things? Even if we dilute aiki down to being this flowing exchange of weightless motion, how exciting can it be for him at this point?
It certainly seems to me that they don't come at him as hard as some of the other shihan. He may not actually have a choice in the matter.
