I had to reset my ID/pass so in basically re-registering on this PC noticed some old threads listed and came back across this one. Sorry, I know it was old but appears I never saw nor answered it.
I have worked out with a few Aikido folks and had taken some seminars in it, as well as Jujitsu. The Jujitsu seminars I attended were with Professor Gary Jones - don't remember the Aikido instructor's name. The Japanese arts I was referring to were Shoto Kan, Shorin-ryu and Shorie Ryu.
Sorry Hawke for taking so long to see and respond to your question.
