Re: Uchikaiten Nage
Wayne, that is exactly right. You have to imagine performing the technique as if you have a sword in your hand. You can even experiment with holding a bokken as you perform uchi kaiten nage. This is called "Ken no tebiki".
I regret having to miss your Sensei's course in Bristol last Saturday. And please extend my belated congratulations on his promotion to Rokudan.
