* During an approach shot, if the green's elevation is higher you should consider
  putting backspin on the ball. Backspin will provide arch to your shot, enabling 
  the ball to elevate to the desired height, plus the backspin accompanied with 
  the arch will decrease the chances of the ball rolling when landing.

* Putting top spin on the ball will give the ball a lower trajectory at a faster
  velocity and it will increase the length of the roll after landing although your
  total flying distance will be shortened.

* For the best results in reaching an elevated fairway or green, use backspin to
  increase your flying distance.
