All things considered, all comments aside.....as I think back over the years I have been around Aikido the one individual who to me represented both grace and elegance in motion is Frank Doran. Upright and straight, moving from place to place with little effort and looking good doing it.........
I had similar thoughts. I was thinking of Ueshiba. He had grace, elegance, speed, effectiveness +++.
Quite a standard to keep referring back to.
