In Mark Wilson's book, he refers to "catastrophic elbow drop", which I took as a mika or Mike Davis stroke. Where if you a are beginning and you try to emulate that you will not be as efficient.
I emailed him about the topic....
I wrote:
One ultimate question I have is on pro grade follow. you advocate the tip pointing downwards on your stroke, but when shooting pro grade follow I have always finished my tip parallel with the aiming point of high cue ball. Is the tip pointing towards the table true for all shots? Or when aiming high should I follow straight through to gain the most follow?
On power draw or power follow shots, many pros with exceptional fundamentals (niels feijen, shane) have a slight elbow drop because of where the tip follow needs to go. And I remember you writing don't copy the pros exactly because you could pick up bad habits that take hours to overcome.
Here was Mr. Wilson's reply:
As the elbow remains stationary the grip hand moves into your shoulder area on all strokes. Shoot some shots and just before the backswing close your eyes and feel for the elbow still and grip hand landing, then open your eyes and observe the tip.
After hours of practice and more players, the slight elbow drop is somewhat natural of you are using a long bridge length, like souquet does. But if in short distances, like straight pool scenario, their elbow will be exactly still with the follow through being not as extreme.
