My name is Scapo. I'm 5'8". Turning 40. And last time I measured, my swing speed was 130 mph. Even though I swing so hard, I'm relatively accurate for the distance that I'm hitting. When I was younger, I had much more wrist lag in my swing and was very wild. Now, I generate speed with rotation and I have a very long impact position with a flat left wrist. Even though my wrists are less active, my upper torso increases speed as it rotates through impact. This creates what I believe is a very powerful whip effect as my left arm approaches the ball. As I get to the ball, it feels like I can hit it as hard as I want with my right hand, and still take the left side of the course out of play. I believe this technique is somewhat rare, because most of the pros I talk to don't believe in this technique. I have a lot of fun hitting the ball well over 300 yards.
P.S. I have special training that I do in minutes a day around my house. Any questions or comments?
