Furthermore, as you know, this article does quantify that late wrist release can increase clubhead speed (albeit less than 5%). In particular, it is advocating exactly the opposite of what is shown by Jack in his video: keeping the wrists angle at a 90 degree angle (or even more, as Tom Guerry likes to note) as late as possible, not "casting the fishing pole" at swing initiation as given in the video.<<<

Ray,

I don't know what the dog on the leash example is, but snapping a towel #3 and using a bullwhip #4 as your example shows is definitely the whip effect. Here, the rotation is supplied by the wrist and elbow joints. Note that the wrist is cocked back and the rotates forward to supply the whip action. Try snapping a towel or cracking a whip without using your wrist. Won't work, at least for me.

Again, Ray, thanks for your link to the golf article some months back. Good post. Helped me a lot.
