Great videos, I'm a fan. However I was a little disappointed at your ukeship at the end of the kokyu dosa section. I'm not quite sure what you are trying to show. You are very centred, but you bend your elbows in close to your body and allow your partners wrists to slide through your hands. This surely is not an honest grip. Of course the guy in nage role cannot gain any traction and perform the technique. The idea of "not letting nage(tori) perform the technique" is a hideous virus in some dojo, and I would hate it to spread.
