Nikon - He did? For the AAF seminar? I didn't see him. heard hombu didn't really want him to go cause of disturbances in indonesia. How that's related don't ask me.
Anyway, I recently noticed that in the tomiki and yoshinkan style, Shihonage is always performed after uke's balance is broken. Those two styles seem to break it by locking uke's elbows until uke is forced to stand on his/her toes. Ouch!
