Re: effectiveness: experience on learning
One of my best experiences training in aikido was, when traveling as otomo to my teacher in my uchi deshi days, we did a guest seminar at a karate/jujitsu school. It was just sensei and myself. While he ran the skeptical students through techniques, I ran around and helped guys and gals having issues with the techniques. It really made me feel good when I was able to get aikido techniques to work on the skeptical karate students. Really cool stuff.
