Chris, if you were training Yoshinkan Aikido in Tokyo when Gozo Shioda was alive, I will take your word over most people's. If there was someone credible in BF Illinois I might give it another shot, based on you and Cliff's say so.
Things might be different now if I'd had access to the kind of instruction you have had. But I am still very grateful for my local teachers, Paul Huber Sensei, and his predecessor Kit Hathaway Sensei, who have hammered us for 9 years with rigorously painstaking kihon. Whatever I do with it from here will be better because of it. So to answer the question of the thread, "Technique, IMO".
