A car hitting something while traveling at one MPH will do more damage than a motorcycle hitting something while traveling at one MPH. Use greater "Lag Pressure". Be a "car". Be a "Freight Train". Heavy, not dainty. To vary the effective mass of a nine iron by increasing the Lever Length, increase your pivot lag. Swing from the Feet. If you swing from the wrists, the Clubhead will slow from the impact force more than if you swing from the feet. Swinging from the wrists may produce enough Mass for Putting, but not for a 2 Iron. __________________ Daryl Last edited by Daryl : 12-26-2011 at 06:27 PM.
