On a related note this weekend was the All Kansai Aikido Championships (Tomiki). I was watching both the male and female world champions (the male also does really well in shoot fighting) and one thing both had in common was a certain calmness when dealing with their opponnent. This of course, especially in the case of Yu (male) translated into an explosive application of technique at the correct moment.
Interesting weekend - the next day was my town's Judo tournament. The All-Japan Juniour High School champion hails from here. Damm he was good. I also couldn't help but admire the physique. You could tell he was just 15 when you looked at his face but other than that he looked absolutely dangerous - not an ounce of extra meat on him. He fought the same way the Aikido guys did - calm, calm, explosion.
