The most impressive things I remember about being thrown by the late Akira Tohei Sensei was the combination of precision, effortlessness and control was such that I basically felt like I had no choice to do anything other than to go exactly where he was putting me. Even though his technique seemed effortless, it was indescribably powerful.
By the way Drew, how'd you like Parkside this summer? I was at the Midwest Aikido Federation Summer Camp there the week before the AAA event. Great food, huh?
