Re George's post above:
In Toda-ha Buko-ryu, we have four shihan. I am "first" among equals only in the sense that I'm first to be made shihan, but I'm not even senior among us. None of us does the kata exactly the same, and that's fine. There will be a next generation soke as well, and it will not be a Westerner, about which all of us, to my knowledge are very happy. A Westerner could not fulfill that post. I do not want to go any further into this, as that would drift the thread.
