Abstract
A set of golf shafts is disclosed. The set comprises a plurality of shafts that decrease in length along the set. Each shaft includes a reverse taper section disposed a distance from the tip section on each shaft. The distance of the reverse taper section varies along a number of shafts as the shaft length decreases. A golf club shaft is disclosed. The shaft includes a tip section, lower section, and an upper section. The tip section connects with a golf club head. The lower section includes a tapered section and a reverse taper section. The tapered section extends from the tip section. The tapered section increases in diameter in a direction away from the tip section. The reverse taper section extends between the tapered section and the upper section. The reverse taper section has a diameter that decreases in a direction away from the tip section. The shaft further includes a resilient plug wedged inside the shaft. The plug extends along the reverse taper section, the plug being formed from a sound absorbing material.
