Many years ago I was also shown by one of his students….one 2-man drill(it was really many years ago
) Anyway, the drill was like an modification of a traditional block/parry-straight punch strike drill I learned in Okinawa, but I was informed his variant(s) of the drill was as original as the one I had learned.
Could actually be. I learned the drill in the GoJu ryu tradition, while McCarthy’s from the Shorin ryu tradition.
The student mentioned that a similar drill is found in Filipino MA too..
