Marc. Enough talking. Enough empirical this and that.
I have met one person on here and shared my views briefly on the subject and we briefly did some bokken work.
I have named the teacher repeatedly and yet you still ask.
Forget empirical whatever and trying to tell me what I should do, if you want to know then when you have the time and are visiting then come see me otherwise There is no more to say really. If one of your students comes over here the same applies. I'm sure we can make him welcome.
More importantly though, I just thought of something. If you or anyone is so interested in my Teacher then it would be wise and even beneficial for someone of good standing and charachter (I know you like those words) to arrange a visit. Someone like Stanley Pranin for example for I'm sure he would be a great resource for information unknown about the 'early' years over here. A new source, more info, you'll love it.
If not then opinions can flourish but unfortunately not prosper.
I would like to come visit you while I am in England in mid April; train and buy you dinner after.
