Re: to be imparted by oral instruction...
Mr. Tisdale is my Dad! Just Ron will do. Glad to be of some help...I think Allen would definately *show* you more of this subject quite well on the mat. Read his posts carefully (and Doug's).
Stevens Sensei has come and gone to the East Coast already, but if you email me through my profile here, I will try to remember to alert you next fall when he will hopefully return (usually in October now).
Ron (missed him myself this year due to work and family, but I hear he is doing well)
