I believe any style should be your own style for the most part. Let's get real, there are only so many ways to throw a punch, kick or defend against someone. You may be able to change the shape of the hand or body position, but the body still only moves in so many directions. Until we grow extra arms or legs and our head evolves to where it can turn 360 degrees our abilities will be limited. Whether it is some form of Karate or my style of choice (Wing Chun), you still have to make it your own. My students may not be able to use my style or use of Wing Chun, just as I may not be able to use the style the same way a guy who is 6'4 245lbs could. This is just my honest opinion. Even as great as Bruce was he still didn't use anything more than what others used. He still had the limitations of the human body. I am sure some Bruce fans will disagree, but again, this is just my opinion and may not mean much. LOL!!!!
