Abstract
A shaft setS includes a first shaft SF, a second shaft SFshorter than the first shaft SF, and a third shaft SFshorter than the second shaft SF. At least the second shaft SFand the third shaft SFeach include butt partial bias layers sand s. Weights of the butt partial bias layers sand sare increased as the shaft is shortened. At least the first shaft SFand the second shaft SFeach include tip partial bias layers sand s. Weights of the tip partial bias layers sand sare decreased as the shaft is shortened.
