As I said above, it's this kind of person who makes me realize that training in traditional martial arts can have real value. Of course, somebody like your sensei isn't going to settle for just any dojo. Do you know if his sensei was LE, military, etc.?My Shorin Ryu Sensei is retired SWAT, and I promise you, he used karate to good effect during his law enforcement career. He and I were discussing Krav Maga one time, as I trained in it for a few months, and he was of the opinion that Krav Maga is effective, but not unique in its effectiveness. He argued that the effective practitioners of the traditional martial arts employ similar principles as those taught in the more modern, military-based defensive tactics curricula.
