Check the listing for details. Radical No Doubt. Color: Smoke / Blue / Purple, Condition: New. Listed at 195.44 USD. Radical No Doubt Pearl Bowling Ball 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. HK22 features enhanced color and clarity by engineered nano micellular phase separation technology, dramatically improving the cover’s translucency. The No Doubt features Brunswick’s innovative outer core technology called DynamiCore. This industry-leading technology is a more durable outer material that yields less compression upon impact increasing hitting power and creating an undeniable difference in sound and pin carry.
