This invention consist of a grip and shaft centerline that is attach to the head so that this centerline will intersect the center of gravity and the centerline of head, and The the head is designed to be symmetrical about a vertical plane that coincides with the centerline of the shaft. The centerline of the head is a line drawn from the center of gravity to a perpendicular line that is on the flat surface of the head or a perpendicular line that is tangent to a curved concaved or convex surface, and is parallel to the ground, and is at the same height as the center of gravity of the head. The sweet spot is where the centerline of the head will pierce the face of the head. This club head includes a highlighted straight line above and parallel to the center-line of the club head. This acts as a sight line to assist the golfer to align the club head to the center of the golf ball, and align the sight line to a imaginary line that goes from the center of the golf ball to its target. The center of gravity location can be changed by changing the weight and weight location of the head mass. | 08-02-2012 |
