Great stuff...thank you for posting! As I was watching, I was thinking about some of the really spectacular and accomplished practitioners out there, and that O Sensei would likely be so gratified to see where some people have taken this art. I don't imagine that he ever thought he was going to be "the very best who ever lived."
Some of the ukemi in this clip is really awesome. There was one breakfall in there from kotegashi I had to watch a couple of times.
IMHO, this is the aikido we should take as a training model, not that of a 70+ years old.
I think we should take both!
