I rummaged through my sensei's video collection and found Miyama-ryu Combat Jujutsu, which I found to be an excellent modern system of Jujutsu. Anybody here care to share some more background info about this style? It is said that GM. Pereira studied some Judo with Kyuzo Mifone and Aikido with Kishomaru Uyeshiba, mixed in some Kenpo Karate and created Miyama-ryu. So this is a Judo+Karate+Aikido mix, However many of its techniques looks very much like some of the Jujutsu Ryuha that my sensei are doing (Hakko-ryu, Takagi Yoshin-ryu, Shindo Yoshin-ryu etc)..techniques that does not present in Judo, Karate and Aikido..
