Answering my own post (bad) but this was posted on a Tomiki aikido study group page https://vimeo.com/97201380
and shows a very interesting demo with a flavor far removed from much of what we see today. This is something we could use a return to - less compliant uke's - techniques that actually look like they are working.
This video is fantastic - I had not seen this video before. Thanks for posting it.
I do not see a problem with an attack and waiting for the technique to be demonstrated. For the purpose of education it is important to have the Uke receive the technique as it were. What this video shows however is the mechanic and physics of the technique being applied with "intent". Both parties benefit from this type of training as do we from being able to enjoy it decades later.
