Abstract
The present invention provides a matched set of golf clubs, wherein each club in a set of golf clubs, irons, woods, or a combination thereof, provides the golfer with precisely the same feel, related to the golfer's swing when the club is swung, and to the contact between the head of the club and golf ball when the ball is hit. In the present invention the clubs are matched dynamically. The clubs will have one or all of the following characteristics: (1) a constant flexural rigidity of each complete iron and/or each complete wood, (2) a constant moment of inertia, and (3) a the center of gravity which is calculated by using a constant force for the shortest club in the set.
