I never had the priviledge of working with Kobayashi Sensei's Aikido, but my Sensei back in Israel, Eli Landau, is probably 260 lb with a touch as light as a feather.
I just heard that Landau sensei is planning on coming to this years Seidokan Summer Camp
here in Michigan. Thought you might like to know in case you wanted to come to the Seidokan Summer Camp
and see him again
Kobayashi's makiotoshi was amazing... it was like being taken to the ground by a feather.
I mentioned this post to Janean Crapo and she thought she remembered you from the Seidokan Summer Camp
in '94. Was that you? Anyway if you get a chance you should come up this June for this years Seidokan Summer Camp
p.s. Sorry about hijacking this post for my own purposes. If you want to talk to me about it I'll be at the Seidokan Summer Camp
this June. Stop by and I'll apologize in person
