I'm thinking that the quote was talking more about the bending and hooking that goes on with the wrists so often in kokyo-ho rather than anything different from what Takeda or Ueshiba was doing.
I don't know about Ark - but I'll try and remember to ask Rob about it when I see him next month.
Thanks. Just to clarify: I thought Aiki-age
was more or less equivalent to kokyu-ho
or otherwise, solo or paired) . Hence my interest in this:
The Aiki-age of Sagawa Dojo is like this. Absolutely no bending the wrists,
So my question was whether Sagawa sensei changed Aiki-age (assuming it is equivalent to Kokyu-ho).
