Ball bats and methods of making the same are disclosed whereby the handle and barrel members are separate structural components, and whereby the handle member is of sufficient length to extend through the hollow barrel member. The handle member is connected to the barrel member at its proximal and distal ends by proximal and distal connectors. The connection between the handle member at the proximal end of the barrel member is by means of an elastomeric proximal connector. The connection between the handle member and the distal end of the barrel member is accomplished by means of a rigid distal connector. The rigid connection of the handle member's distal end to the distal end of the barrel member and the elastomeric (flexible) connection between the handle member and the proximal end of the barrel thereby allows the handle member to flex substantially across its entire length during ball impact.

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.
