Does this video show a lack of understanding of the differences between hand motion and wrist motion? TGM chapter 4-D explains well. The hands driven through impact. Using the wrists is "hacking"? Why anyone would TEACH a flick (wrist motion) through impact is a question I would have. Hinging is a hand motion? I think HK had a great understanding of this and is the most important machine concept.
