Jim's opinion of Sekiguchi Ryu not withstanding, the group and it's leaders are held in fairly high esteem by other members of the Budo community.
Jim I would ask you not to bring that argument to this forum. I know your feelings on the matter, but you know that what I said above is true. While you personally have had problems with the Sekiguchi Ryu folks, their reputation amoungst the larger budo community stateside is really about as good as it gets.
To the original poster, not many folks on this forum have a lot of first hand experience with the Sekiguchi folks. A few do though. Dave Drawdy-sensei(Socho) does. You might want to retry this query over at
http://www.e-budo.com and
http://www.swordforum.com A search of the archives at those two forum sites would also prove fruitful.
