I don't recommend this solution. Leaning forward like he does can cause chronic shoulder pain in the player's bridge arm over time. It also puts pressure on the front leg and knee. I would consider this position to be an off-balance stance with the weight distribution leaning too far forward. The player is already bending forward at the table. Why add more to it?
This is a GREAT stance. Well done! As for your upper arm movement, that's a good catch. Mainly, what happens in the forward motion is more important, but changing the angle of attack during your stroke isn't such a good idea, even if it stays constant through your forward motion. Try to think of your arm as a hinge below your elbow as you move it back. Right now you're moving your entire shoulder during your backstroke.
This is something that is absolutely standard on a pendulum swing where your upper arm doesn't move. You have a very long backswing. Your hand has to rise a lot unless you drop your upper arm on the backswing and then raise on the forward swing. One issue with that is that you have more chance to come offline either going back or coming forward. You could try shortening your bridge which will reduce the possible swing. A shorter bridge will also reduce the required length of cue stick.
I’m 6’3” and have tried a lot of things to compensate for my height. One thing that works for me is to get my head and eyes closer to the cue ball And not hang back. It helps with aim, shot making and position. I actually have a ‘softer‘ shot. I wish I could demonstrate what I am trying to describe.
Next time I‘m at the pool room I’ll have someone take some photos. It will be about a week from now. Stay tuned.
