I think these are areas that you have expressed your understanding of here on Aikiweb, especially sword and bokken. With that background these seem to be questions that best could have been ask in person while Dan Harden was in London recently. You could have had your answers first hand so to speak.
My questions are quite apt for a forum. Those questions don't need personal meeting. You still go on about first hand experience. I don't need it. I don't need first hand experience of taikwondo either or many other things. So I'm missing your point once again.
