Mark said something very interesting on his Knowledge video about feeling that you never uncock the left wrist thru impact. His main thesis is to never unbend the right wrist and feel like you never uncock the left wrist.. In his swing, he talks about swinging the arms on plane. A laser on each end of a shaft is conventional up until impact, where the beam of light coming out of the clubhead end points along the plane line for infinity. the shaft at finish is tipped over, or matching the spine angle. A beam coming out the grip end of the shaft never points at the plane line past impact. In other words, with your butt to a wall, the clubhead never touched the wall at any point in the swing. I hit some shots late yesterday with this hinge method. I am still waiting the for ball to land.
