ABSTRACT:
In accordance with the present invention, this method encompasses a shaft with a neutral flex point mark and identification mark/sticker of quantitative characteristics that has been achieved by deflecting a shaft, at its tip, a specific distance while resting in a free floating position. Shafts are then sorted by the quantitative measurement of its propensity to bend(flex weight) into sets of shafts to be assembled into golf clubs by aligning the neutral flex point mark on the golf shaft to the neutral point mark on a golf club head.
