A lot of my thoughts on the blurring of the roles of uke and nage come from the Shochugeiko intensive at Chuck's dojo that I attended a few years ago. And, yes, his randori video does provide some good points on the matter.
I should be seeing Bryner sensei in November. I may have to ask him to bring some of his videos if he still has them. Yes, he was at the Aiki Expo; I was able to chat with him briefly there.
I haven't seen Saotome sensei's latest video. I'll have to put that on my "wish" list...
Thanks for the recommendations!
