This is a good driver for older golfers.  The senior shaft is more flexible and lighter than standard shafts which means you can get more speed out of the swing.  If works well with golfers who have a swing speed between 75 and 85 mph. The 40 gram shaft is best suited for golfers who have a smooth swing.  The low kick point helps you get the ball airborne more quickly.  The 10.5 degree loft is appropriate for most golfers.
