Just trying to be of service....and yes, I can tell a lot from a video, and I really want you to play better and find enjoyment in pool and all things. :smile:
I already very much enjoy playing pool. And when I run the occasional 100 I enjoy it even more. (My personal goal is to run 100 two days in a row so I can legitimately call myself a 100 ball runner
What I needed to discover, on my own, was the role my left arm needed to play, not my left foot. That is what has really improved my game the most in recent memory along with making subtle alterations and understanding why they're important. You say you can be of service yet what you recommend would actually hurt my game and send me down a poor path. Having taken lessons with Ray Martin and Dallas West, I can say that at least those two gentlemen had the good grace to observe me for an hour or two in person before offering any mechanical advice.
Like I said, I know you only had the best of intentions when you posted a link to the video ;-)
