I meant the "categorizing" part.
If it matters, I got my ni-dan from Saotome back in the '80's and then spent a number of years in Japan, where I trained with a number of people in a number of arts - but so far I've always come back to Yamaguchi related lineages.
So...most of my instructors have been one step from the Founder.
Saotome's resume (http://en.wikipedia.org/wiki/Mitsugi_Saotome
) sounds like a standard, postwar, Kishomaru/Tohei, student experience.
"There are now two people that I can talk to. They are Yamaguchi Sensei and Saito Sensei. Their forms are completely different, but it's good study for me. They both have something I don't have. Technically, Yamaguchi uses the ken and although Saito Sensei uses the ken too, you could almost say their approaches are opposite. Saito Sensei is the only person who can hand down O-Sensei's Aikido exactly as it was."
According to this quote from Nishio, Ymaguchi was doing his own thing.
Perhaps this is why, you don't find the Founder's Aikido in yours .
