An improved design for a golf club shaft and method increases stroke accuracy by significantly reducing stroke take-back distance. A ball traveling at a set initial velocity will travel a different distance on different parts of the course due to the friction of the grass on the ball which varies in response to height and moisture level. An inline weight management system that allows the moment of inertia of the club to be adjusted in a predictable manner. An increase in the moment of inertia translates into an increase in force which is in turn proportional to club velocity and resulting ball velocity. As green speed decreases, moment of inertia can be increased so that a stroke with a uniform take-back distance will deliver a shot that travels as far as the same stroke would deliver on a fast green.
