Interesting Tommy Carruthers is teaching online Jeet Kune Do classes. These look like an great deal financially, I have seen Tommy Curruthers in person and watched him teach. He is a great instructor and this looks like a great way to learn if you are not in reach of training with one of the top teachers of Jeet Kune Do.
It is the opinion of the Karate Critic that if you are not able to train with a top instructor leave JKD alone. It is hard to find a good practitioner let alone a good teacher and Tommy is Both in Spades.
Jesse Glover compares Tommy favorably with Bruce Lee himself.
