I chose Kajukenbo because I wanted to study a MA that combined both striking and ground work (if you are not familiar with Kajukenbo, it stands for "Ka - Karate, Ju - Judo/Jujitsu, Ken - Kenpo, and Bo - Chinese/American Boxing).
I studied Kajukenbo with Sifu Al Dacascos for a number of years. I never found anything in the curriculum which addressed groundfighting in any realistic fashion. Nothing. Which branch of the family tree do you belong to?
