It makes perfect sense to me! I can totally relate to the idea of the teacher matching you and drawing you out at every step. That is what Gleason sensei does and teaches quite well. You are constantly receiving as uke and nage.
I actually got to train with Sekiya Sensei as my partner in Boston once! When he visited the area (one of his deshi had originally come from the area) he came to the annual Saotome sensei seminar at Gleason sensei's dojo. He had a dark black mustache and a big white afro. It was just ridiculous getting thrown by him. I had no idea what he was doing! He was totally soft and totally powerful.
Also, I believe that Noguchi sensei was the person who taught Kashimashinryo to Gleason sensei. He always speaks very highly of them.
I'm sure that explosive power is very interesting and useful, and I will continue to research it as a side curiosity while I stick to Yamaguchi sensei's approach. It obviously works quite well without focusing on kokyu divorced from aikido training in general. If someone wants to focus primarily on kokyu, I hope it works for them. (Maybe they should call what they do kokyudo?
