Title: Bowling ball

Abstract: A solid bowling ball contains a top weight distributed along a weight plane and underlying indicia on the top surface which designates the position of the weight plane. The top weight includes two major masses spaced apart a distance such that the top weight commences and ends within less than 180 degrees of curvature. The top weight offsets the weight loss resulting from forming the finger holes and also produces a gyroscopic stabilizing effect when the ball is rolled along the plane of the top weight.
