I haven't met you, but I respect what I have heard and what I've seen of those who have studied with you.
The randori we do in Jiyushinkai is very similar to what you've described done by Mr. Vasiliyev in Canada. It's difficult to do and still maintain "combative reality" when going slow. As skill in the practice method increases, we can speed up and use full force attacks with strong intent. Of course, this requires very good ukemi skills. Thankfully, by the time someone in our system approaches this level, the tools are there.
If you're ever in the Tempe/Phoenix area, please drop in for a visit. I come to the Seattle area frequently to practice jo with Relnick Sensei in Woodinville. I'd like to get acquainted.
