I just had a Lesson with Ben Doyle. More on that later. I was "left Arm Swinging" and Driving the Ball about 255 Yards. Another guy was Swinging and Driving the Ball 300 Yards. I asked Ben "What's going on?". He said the other guy was "Right Arm Swinging". We put him on video and sure enough Ben said, "See, he gets all that power from his right arm". I asked "is he still swinging then?" and Ben said "Ya, a right arm swinger". Enough for me.
