Each shaft is then fitted to the chosen clubhead and tested on a frequency analyzer at the selected length that the club will be when complete. The shaft is then cut to size keeping the same cycles per minute constant with every shaft. The golfer now has a set of clubs that have the same shaft stiffness throughout. Only now can we reproduce the same ball flight with the same repetitive motion. The results are more solid ball striking and more consistency.
Many golfers have a favorite club in their set.
Usually it's the club they hit the best. Most often this club's shaft frequency is the one closest to what their flex should be. Simply, golfers hit it best with the club that fits them the best. The only way to assure that you are buying the right equipment is to be clubfit by a professional This is done by having the golfer hit identical clubs on the driving range with the only difference being the frequency and length of the shaft. The trained clubfitter studies the flight of the ball and where the ball flight begins.
