Uechi Ryu, Shorin Ryu, Goju Ryu, and SHito Ryu are all Okinawan karate styles. They are all pretty similar with only slight variances as far as i have been able to tell. I practice a version of Shito ryu call Shukokai and have friends that do Goju and Shorin. Sanchin is actually a breathing and tension kata. Have never heard that it can cause high blood pressure before. thats a new one.
