Re: best aikido you have seen
I have seen many Aikido teachers - the best for me was Terry Ezra (UK) becuase he would really try to show you how to do what he could do (not that I could). Others just show you what they can do.
Other greats I have seen were Master Sken of Muay Thai, Mr. So of Bagua (Tokyo), Dan Innosanto (Escrima), and two or three amazing Silat teachers - incredible men. One of the most fascinating martial arts I have seen - several times - is Indian Kalari (takes you back to the past - lineage means nothing as it comes right up to the present; it shows that youngsters can be real masters of a battlefield art).
