A special purpose calculator for determining the optimum degree of flexibility for a matched set of golf clubs, tailored to the driving capability of the individual golfer. The calculator first correlates the effective driving capability of the individual to an empirically determined optimum flexibility index, which index is based on a standard club length, hosel length, tip insertion depth, and swing weight of the golf club. The calculator next compensates for desired differences, in for example club length and swing weight, to determine a shaft with a compensated flexibility index which will provide the same "feel" as the standard club. The calculator can then also be used to determine the requisite head weights, both wood and iron, as a function of desired club length and swing weight so as to provide the proper flexibility for that individual. For optimum results, the flexibility index is determined by measuring the vibration frequency of the shaft.
