You are right Jim when you say none of us swing the club exactly like Mindy. Everybody is built with different height, flexibility and so on. So it is impossible to look exactly like the way Mindy was swinging the club. But we can always try to achieve, with the best of our abilities , the different positions and feelings that he is describing throughout his swing. My downswing is started with my lower body, my legs feel and react like a platform because the pressure inside my trail foot is staying longer than when I used to swing the conventional way. My weight is not shifting to my forward foot as fast but rather staying centered in between my feet, it feels slightly like a reverse weight shift because of the pressure felt inside the trail foot. This is how I get the feeling of hitting more with my trail shoulder as hard as I can. The speed of my legs and hips is eventually transferred to the upper body. The faster the lower body reacts, the more speed is delivered to the shoulders. If the hands position at the top is well achieved with a good deal of weight forward with the hips at the right position(parallel to target), and if the sequence of the downswing is done properly with a good deal of pressure felt inside the trail foot, the hands should not do anything but keeping the initial pressure, my trail arm will feel more across my body throughout the impact zone and the dragging sensation will be felt.
Learning a new swing is a real challenge. I believe, the most difficult part of learning the reflex swing has been turning the shoulders while the hips are going the opposite direction. Have you had the same Challenge ?
