The No Doubt Solid features a Super Symmetrical core with an RG of 2.485 and a DIFF of 0.051, now enhanced with the sensational HK22C+ cover. The HK22C+ cover includes the Cohesion Additive, a traction-enhancing additive that makes the No Doubt Solid more responsive to friction. These Super Symmetrical balls provide a wider range of after-drilling differentials, bridging the gap between Symmetrical and Asymmetrical balls. We have further improved performance with the HK22C+ Solid cover. The core dynamics and after-drilling potentials make the No Doubt Solid a strong, versatile ball
