Abstract: Golf club heads with improved aerodynamic properties. In an example, the golf club head has striking face; a sole connected to a bottom side of the striking face; a crown connected to a top side of the striking face. An aft slice of the golf club head includes a rearmost point, a toe-side aft slice on a toe side of the rearmost point, and a heel-side aft slice on a heel side of the rearmost point. The heel-side aft slice has a volume greater than a volume of the toe-side aft slice. The aft slice is defined as a portion of the golf club head to a rear of a slice line and between an outer perimeter of the golf club head and an offset perimeter slice curve.

Abstract: Golf clubs with improved aerodynamic properties. In an example, a golf club has a golf club head; a grip; and a shaft having a tip end and a butt end. The golf club head is coupled to the shaft at the tip end, and the grip is coupled to the shaft at the butt end. An average bending stiffness of a butt end portion of the shaft is greater than 3.70 times an average bending stiffness of a tip end portion of the shaft.
