To get the most distance from your driver, you must optimize the launch angle and spin rate of the ball by selecting the proper loft and shaft flex for your swing speed. Generally, golfers with slower swing speeds require more-lofted drivers and more-flexible shafts to achieve the proper launch conditions. Conversely, golfers with faster swing speeds generally require lower-lofted drivers and firmer shafts.
