How can I make sure that I have maximim clubhead speed?
Take your club and flip it upside down so you are gripping the shaft at the clubhead end. Take some full swings whipping the grip end of the club. The club will make a swoosh sound. You want this sound to happen past your front leg. If your swoosh happens by your back leg you are losing your hinge or lag in the golf swing and some would call it casting the club too early. Without getting technical, just start swing the club as described above and you will be surprised at how quickly you can move the swoosh to where it needs to be.
