I feel that there is another point that Furuya Sensei brought up that I noticed in a number of public demos. Furuya Sensei mentioned showing basics that show what the art and at the same time gain interest in the art is while doing these documentaries. IMHO many of the demos that I have seen show flashy, powerful aikido that, while generally well done and quite impressive, leaves the audience saying "I can never do that". What looks good to us is different from people that are being introduced to the art and sometimes we need to simplify to get these people to join. In our dojo we depend heavily on public demos for recruiting because at a university we lose people to graduation all of the time to keep enrollment up. We have found that when we get flashier and more advanced the less successful our recruiting has been. Just my $.02.
