Hello Mike!
Welcome to the forum! I sincerely hope that you will visit here and post often! In response to your comments regarding Bruce Lee's movement with the pak sao da in Enter The Dragon, that was what we refer to as a "speed pak". In other words, just a very fast trap used to remove an obstruction from the line, combined with a very fast hand technique such as the qua chuie used by Bruce Lee in that sequence. I too noticed (long ago when I first saw "Enter") that Bruce used his waist and hips with the pak/strike. Bruce Lee was a master of body mechanics! We can only hope to achieve that kind of mastery over our bodies one day!
I have read the four part series with Hawkins Cheung that was published in Inside Kung Fu magazine many times. That is where he first mentioned "pak sao and hip". I felt that the things he had to say were inportant enough to include in my manual that my Instructors/Instructor Trainees get when they join my organization, so all four parts of the article are there word for word. There is much good information there as to what Bruce Lee really wanted Jeet Kune Do to be! I also have the three videos that Hawkins released. Although they are interesting, I wish they were less talk, more show, if you know what I mean! I enjoy learning about peoples ideas and the history of things, but I am more of a "learn by watching and doing" kind of person! I will have to say though that some of the most important things that I have ever learned about Jun Fan Gung Fu and Jeet Kune Do were during quiet conversations with First Generation students of Bruce Lee!
Once again, welcome to the forum! I hope we will see a lot from you on here! My personal best to you always!

Keep Blasting!

"What is Jeet Kune Do (JKD)? Chinese martial art, definitely! It is a kind of Chinese martial art that does away with the distinction of branches, an art that rejects formality, an art that is liberated from tradition." __Bruce Lee
