I liked your story about the Ki balls.
In my view that could still be classed as a no touch throw. The instructor spun the story about the Ki balls and used his presense as an instructor to convince the uke that he should fall down.
had I stood up and done the same thing the Uke would have just stood there, but it took alot of training and building up of a reputation to convince the uke that he had little choice but to fall down.
good technique, worked on for the course of many years
as for no touch throws, I have never pulled one off myself, but I have experienced it before. it was amazing. I have to agree with Thalib that it was more like being mezmirised.
My attack was real, and I think the thing that threw me was my own belief that I was actually going to make contact so my energy kept going and tried to follow him. then he just took it away completely and I flew
it was so much fun, and amazing to see someone move like that
