In purchasing a driver one must consider the amount of suppleness and flexibility in the shaft and also where that flexibility is located. A fine, steely spring is what is wanted ; or just enough spring in the six to nine inches above the whipping to feel the shaft give when the club head strikes the ball. To get the proper amount of spring, much depends upon the weight of the head, a heavy head giving the right amount of flexibility to a stiff shaft, and too much flexibility to a limber one. The head, however, should not be so heavy that it makes one's natural swing drag, or so light that the strength which might have been put into the swing is partly lost and the club checked with its concussion with the ball. By the principle of the lever, the longer the shaft the heavier practically is the head; and for this reason one who uses a short shaft generally plays with a heavier head than one who uses a long shaft. This weight of the head, in connection with the length of the shaft, is what is called the balance of the club and this factor must be considered before deciding if the club has the right amount of spring and if the spring is in the right place. In picking out a driver see, therefore, that the club has the proper lie ; that it is properly balanced to your style of swinging; and, if these two conditions are right, that it has the proper amount of spring and that this spring is near the whipping. Remember that if your swing is slow, there should be enough weight in the head to make up for loss in velocity; also that the common error is in having too heavy rather than too light a head. See, too, that the shaft is not too flexible, the best golfers using rather stiff shafts because, with much spring in the shaft, there is less certainty of hitting the ball true.
