In trying to improve my weight shift from address to back foot on the back swing, I inadvertently introduced a sway. As a result, I was seeing inconsistent striking and loss of distance. Plus, when warming up, i was hitting everything fat. Definitely frustrating. Then, I figured out that a less exaggerated weight shift kept me centered over the ball and eliminated the sway. Ball striking and ball flight were dramatically improved. Distance came back too. Glad I figured it out myself.
