ABSTRACT:
Method of producing matched golf clubs comprises steps of determining under similar conditions frequency of each golf club shaft of plurality of shafts. Shafts are selected from plurality such that frequencies thereof fall on predetermined gradient formed by plot of shaft frequency and shaft length. Frequency increments between successive shaft lengths along gradient are substantially equal. Subsequent mating of shafts with selected club heads produces integrated and correlated matched golf clubs. Matched set of shafts and clubs is also described.
