Tohei moves as he thinks.

One is a sphere, one is a spiral.
Interesting point; although I knew they were doing something different, I never looked at it that way, but you are right. Another interesting note is that what Tohei is showing is approved and endorsed by Kisshomaru - however, a few years later after the split, Tohei is still doing the same stuff and Kisshomaru will have none of it and takes 'ki' out of all main stream Aikido
