I was about to say, I would have thought you would have trained with them. But then I though, Yoshi was more of a Karateka, so he might not have been to heavy on the Judo. Didn't he teach kids judo?
PS Yes, his name is Allen, or maybe Allan, or Alan... I don't know
Just looked him up, Allen it is.
I asked Allen to show us a few judo techniques one day but we never got around to doing anything.
I did learn the basic judo throws, chokes, locks and drills you see in Mochizuki's book however Yosh was a stickler for basics so we didn't venture out too far from kihon. I know he taught judo at UWA to the state team so he probably taught kids judo too. I just never heard about it.
Thing is although we had the karate, kenjutusu and judo elements in aikido we never really concentrated on any one of them for too long. It was always aikido. So I did separate classes in Yoseikan karate kobudo and iaido. Unfortunately at that time Yosh wasn't teaching judo as I would have signed up for that one too.
