What is so tough about tracing a straight line from at least hip to hip?
Moe's real swing was never taught by the Natural Golf folks- they spoke of a single axis and always claiimed the left arm and shaft where on plane, clearing they knew nothing of the flying wedges (but who outside TGM did). Moe is a friend to this forum. As for planes. Everyone must get back to the elbow plane before impact (right forearm magic) - if you stayed on it for the entire swing, your arms would just wrap around your waist. Its all in the hands
