The ZigZag Solid is a strong, continuous Asymmetrical ball with an RG of 2.501, a total DIFF of 0.045, and an Intermediate diff of 0.015. The core in the ZigZag was designed to allow a greater change in Differential numbers after drilling. The total Differential range after drilling can be as low as 0.030 and as high as 0.057, and the Intermediate Differential has a range of 0.010 to 0.030, making this a unique and versatile performance ball.
