Whoa! wait a minute...
I can understand that if you are on the spiritual development side of the track, that type of risk is unacceptable but you do need to realize that there some of use that practice for the martial aspect and that the risk of injury is perfectly acceptable, especially since we do it in a controlled environment.
Ok, I've trained with Don...he is not from any "camp". He has some excellent waza, and excellent ukemi. For those who doubt it, buy the Friendship demo where he takes some INTENSE ukemi from Saotome Sensei in Japan. Don has every right to his opinion, as does Ellis (Original Graduate of the School of Hard Knocks).
Look, different people will have different opinions of those clips, of the clips of Shioda, etc. I know for a fact that there were yudansha that were praying Shioda Sensei wouldn't call them up for ukemi. Yoshinkan can be a very rough style, and just because someone has excellent physical skills doesn't mean they will embody the "peace and love" ethics of post war aikido. As long as the person signing up for the demo is aware of what's up...that's between them and their instructor.
Ueshiba Sensei put Shioda Sensei in the hospital for 3 days...after trashing the arm of the first uke in the demonstration before the emperor. That is some rough stuff...as Shioda Sensei was the founding member of the OGSHK himself
. It is what it is. No need for any of us to be casting aspersions on the people who are making valid comments.
That doesn't mean I have to agree with them, or to take it as seriously as they do. But both Don and Ellis are buds, and I can't sit by and watch people mis-characterize them. Especially since I've felt and seen their waza, and know they don't match what some people have said.
