I setup a station, as per Dean's call, other posts here, and then reviewed Hogan book again. Net - After only a few shots, I experienced much better ball striking and velocity, on a more consistent basis. Now after just three range sessions, the improvement is sticking and very noticeable. For me, the big one seems to be placing the ball 2-3 inches behind the lead heel, on all shots. I had slipped into the mindset of putting the ball in the middle of my stance for any shot off the grass. I was thinking it helped with a descending blow. But I think my brain was simply compensating for the ball in the middle by holding back the weight shift. Now with the ball forward, I can be more forward and aggressive with the turn and front let pivot.
