Yes, I see that now, thanks. "Technical aspects" = pure techniques. Locks, strikes, kamae, etc. What's contained in the kata, I suppose, though I say that because of context clues in other posts. I've no personal experience with Koryu. By way of example- when I was preparing to move to GA from VA ages ago, I was looking for places to train martial arts, one of which promoted "traditional" Japanese martial arts. After exchanging e-mails with the instructor, he claimed he wouldn't teach me because I wanted to train with him concurrently with a more progressive system, and said something to the effect that I wasn't "dedicating [myself] to learning" his material. I'm wondering how common that attitue is. I'm a martial mongrel, and while I respect and enjoy all the martial arts I've trained over the years, I train to better my understanding of martial arts, not to preserve someone else's tradition. Now I'm not the sort of guy who goes into a Goju-Ryu karate class talking about how great my Wing Chun experience was, or goes into a BJJ class talking about how Catch Wrestling does things- I go there to learn what's being taught, and unless I need technical clarification, I keep my mouth shut. But, would the Koryu community frown on someone who, like me, would only want to attend classes in order to focus on how the techniques could be used for a practical purpose?
