Well, if you actually knew something about Jeet Kun Do you would realize that its not a style. It is a philosophy born of pure effectiveness, it is a culmination of concepts that work for you. My JKD is different than your JKD, and Bruce's JKD. So with that said here is my list: 1 Krav-basic and effective enough for anyone to use 2 JKD- for more advanced practitioners 3 Progressive Karate 4 BJJ 5 Joe Lewis Kickboxing 6 Kali/Arnis 7 Silat 8 Kung Fu 9 Ed parker Kempo 10 Kodokan Judo I have used a mixture of all of these styles in my training and I have never lost a fight.
