A question for the scholars of Aikiweb. It is well documented that Tohei upon arriving in Hawaii had to reformulate his mechanics to deal with 300lb Samoans, and (I assume) to a lesser extent, large Americans. Did any of the other shihans responsible for spreading Aikido to the west publicly acknowledge their own "reformations" or is Tohei unique in that respect?
Somewhere on the Aikido Journal site (I had let my subscription to AJ lapse so I can't locate the exact link) there is an interview with Yoshimitsu Yamada where he states that when he came to the US he had to make his movements larger in order to effectively throw the larger Americans. I believe it is from this that we get Yamada's trademark large,flowing aikido movement.
