There is a video on youtube: "3 Major Schools of Okinawa Karate - Uechi-ryu, Goju-ryu, Shorin-ryu Vol.2" These is some interesting material on there.... I think...... but I don't know where material about one style stops and another begins. I don't even know who's on first. If someone can help sort this for me, I would appreciate it. Thanks.
