Abstract

Golf club fitting systems and methods include: (a) receiving input data indicating a golfer'"'"'s driver loft angle and shaft flexibility characteristic; (b) determining initial candidate fairway wood clubs based on this data; and (c) identifying the initial candidate fairway wood clubs. Such systems and methods further may include: (d) receiving launch monitor data generated when the golfer hits balls using the initial candidate fairway wood clubs; (e) determining and identifying additional candidate fairway wood clubs for testing; (f) receiving launch monitor data generated when the golfer hits balls using the additional candidate fairway wood clubs; and (g) determining and identifying a recommendation for a final first fairway wood club based on the data. Other clubs in the fitted set also may be determined by these fitting systems and methods.
