Product Description Get ready to revolutionize your game with the DV8 Bowling Heckler bowling ball, DV8s groundbreaking leap into asymmetric technology for the world of no-thumb bowling. Following the legacy of the proven symmetric Trouble Maker series, the Unholy core is brand new and specifically engineered for oily conditions, offering unparalleled performance for the no-thumb audience. The Unholy core was developed for two finger holes to manipulate drilling numbers more effectively than traditionally designed cores. The HK22 cover with Cohesion and Maximum Havoc additives was strategically chosen to match up with the Unholy core to dominate oily lanes. The good news for traditional bowlers who use a thumb is that the Heckler doesnt discriminate, just like the Trouble Makers; youll love this one, too.
