The core in the Zig Zag was designed to allow a greater change in differential numbers after drilling. The total differential range after drilling can be as low as .030 and as high as .057, and the intermediate differential has a range of .010 to .030, making this a unique and versatile performance ball.Color: Black/Purple/Grey *Please note that colors may slightly vary from image shownCoverstock: HK22 Solid ReactiveWeight Block: ZigZag Asymmetric with DynamiCoreFactory Finish: 500, 1500 Siaar Micro PadFlare Potential: 4-5″+ (Medium-High)Radius of Gyration (RG): 2.501Differential (Diff): 0.045Intermediate Differential (Mass Bias): 0.015WeightRGDiff.Interm.
