Really nice demonstration of some American Kenpo. I think this is pretty close to the epitome of modern karate. No, I don't do Ed Parker Kenpo, but if I were to start over in karate and had the opportunity, I'm pretty sure this is what I'd choose to be doing. As it is, I study Parker's Kenpo thru books and video, seeking to apply his principles to my karate and I think it would do a lot of modern karate folks a lot of good to do likewise.
Of particular interest to me is Planas' demonstration of Shield and Mace, beginning at 2:00. Notice that this is a very direct and very elegant bunkai for parts of Tekki/Naihanchi. I think if you look carefully, you'll also recognize the circular motions in Sanchin or Heian Sandan.
