The No Doubt features a newly designed Super-Symmetrical core. Our goal was to create a ball with Asymmetrical characteristics yet a longer hook window so it could be used on a greater range of lane conditions by various styles. The key here is that we designed a Super-Symmetrical ball with a core that will maintain axis rotation longer, making it less likely to roll forward at the end of the pattern. With an RG of 2.485 and a Differential of 0.051, the No Doubt is strong enough to handle medium patterns, and most importantly, we love the way it goes through the pins.
