I think this quote from Bruce Lee examplifies the tenets of Form VII: Jeet Kune Do favors formlessness so that it can assume all forms and since Jeet Kune Do has no style, it can fit in with all styles. As a result, Jeet Kune Do utilizes all ways and is bound by none and, likewise, uses any techniques which serve its end. The last sentence is very important because in Mace Windu's form of Vaapad it takes the practioner to the very threshold of the dark side. The whole mentality of using anything to win. Another thing for the form VII/JKD argument is that it is so hard to pin down to a simple form. That in itself lends credence to JKD being the 'form' for Form VII. The whole point of JKD is to transcend boundaries, to be fluid, to be water. When you dive into a pool you cut into the water, when you do a belly flop the water hits back. Form VII is all about adaptation, becoming what you need to to win the fight and using whatever you can to win.
