- No Doubt

First Impressions
Radical's No Doubt arrives in October 2024 as a distinctive addition to the Reliable Performance category, dressed in an eye-catching Smoke/Blue/Purple color scheme. The visual character comes from the HK22+ Pearl coverstock, developed with nano-micellar phase separation technology for improved translucency and clarity. The ball features the newly developed Super-Symmetrical core with an RG of 2.485 and a differential of 0.051 in 15 pounds. The surface comes from the factory polished with 500/1000/1500 Siaair and Crown Factory Compound. One notable feature is the implementation of Brunswick's DynamiCore technology, which serves as an outer core layer and should reduce compression at impact, thereby delivering increased carry and the characteristic sound. The color placement of the logo was designed so that the different phases of ball reaction — skid, hook and roll — become visually traceable.
Comparison Compared directly to Radical's Deadly Rattler, the No Doubt shows roughly 2 to 3 feet more skid while at the same time producing up to four boards more total hook. Where the Deadly Rattler is wrapped in the HK22 Pearl coverstock, the No Doubt uses the further developed HK22+ Pearl formulation. The decisive difference, however, lies in the core: the No Doubt uses the new Super-Symmetrical core, while the Deadly Rattler employs the classic Rattler Symmetric core with a lower differential (0.035). This core construction gives the No Doubt characteristics that come across as asymmetric while also widening the hook window. Within the Radical line, the No Doubt positions itself as a versatile symmetrical pearl option that offers more backend potential than classic symmetric pearls. The particular core property of maintaining axis rotation longer sets it apart from conventional symmetrical constructions and reduces the tendency toward premature forward roll at the end of the pattern.
On the Lanes The No Doubt was designed for medium oil volumes and should play to its strengths best there. The HK22+ Pearl surface allows clean travel through the heads, while the Super-Symmetrical core provides substantial traction in the midlane. At the breakpoint the ball unleashes a pronounced angular move with continuous backend reaction. Thanks to the special core geometry, the layout spectrum offers expanded possibilities: with the recommended Max Flip drilling, values of 0.059 total differential and 0.014 intermediate differential can be reached, which increases the dynamics even further. If you throw around 14-15 mph with a rev rate between 250 and 300 RPM, expect strong backend motion and excellent pin carry, according to reports. The ball responds well to surface adjustments and works on house shots as well as sport patterns. For bowlers looking for an aggressive symmetrical pearl option with a pronounced backend that still needs more hook potential than conventional symmetric pearls, the No Doubt is an interesting alternative. The combination of extended skid and strong movement off the friction makes it particularly suited to situations where the ball has to be sent deep into the friction without rolling out early.
