ABSTRACT:
The present invention relates to methods for optimizing the flexibility of each shaft comprised in a set of golf clubs. In general, based on a golfer's estimated swing speed, skill level and/or other relevant factors, an appropriate category of golf club shafts is selected. Each category of golf club shafts employ a unique range of shaft flexibility. The range of flexibility exhibited by categories of golf club shafts optimized for golfers with relatively higher swing speeds is greater than the range of flexibility exhibited by categories of golf club shafts optimized for golfers with relatively slower swing speeds. Similarly, the range of flexibility exhibited by categories of golf club shafts optimized for golfers of relatively higher skill levels is greater than the range of flexibility exhibited by categories of golf club shafts optimized for golfers of relatively lower skill levels.
