Open Question: does anybody know of any martial arts based on jeet kune do?

There are thousands...(really).
Many instructors trained in the principles of JKD find their own 'way' of expressing the ideas. It isn't really JKD at that point so they call it something else.

I have already found the Keysi Fighting Method, Combat Submission Grappling and Progressive Fighting Systems and wanted to know if there were anymore.
