The Hamilton Sensei Seminar (http://www.sho-ha.com/ryu/) was truly enlightening. Kogawa Bushido Kai was exposed to sai technique not experienced in the past thirty plus years. It was a pleasure experiencing such effective yet simple sai applications. Of course part of the application was supported by well controlled fine and gross motor function.
Several Yudansha will be visiting Mr. Hamilton this December to further our training.
