I am not sure since I have been to his seminars but our instructor uses a lot of what is on the tape...he says.
The Seisan tape has some good stuff on it, paticualrly grappling. At least I think it is the Seisan tape.
I 've been shown a few things by Mc Carthy, we sue the tapes, but I haven't watched them. All I know is some stuff he showed us and some on the tapes we didn't see at the seminars is practiced in class.
Anyway, I can offer you an opinion....he is a great resource. Anyone who doubts classical martial arts will be "visibly shaken" after attending a seminar of his.
