The lead shoulder movement to start the backswing makes or breaks the swing, at least for me. It is VERY easy for the lead shoulder to drift off to the right, THEN rotate down. But by that time, it's too late. The damage is already done in terms of my weight shifting onto my trail foot. Then the rest of my swing shifts into recovery mode. Fat, thin, pulls, you name it.
I now envision a wall that runs down the center of my torso at address. From there, my lead shoulder cannot hit that wall to start the backswing, it must travel more "down and to the target side of the wall". I feel very tilted but I'm not. I'm simply stacked over the ball.
@GolfLivesMatter Stacked and tilted over the ball is critical. I’ve been studying the Inner Game of Golf and applying it to my game. Focusing much more on what I’m Feeling in the swing. I have been able to increase ball contact for example, by my maintaining awareness of the feeling of my right upper arm rubbing lightly against my mid body in the backswing.
