Radical’s Guru Oracle Pearl shares the Guru Asymmetric core shape with the Guru Oracle. The big changes are to the coverstock and the surface preparation on this new release. Instead of a 500/2000 SiaAir finish on a solid coverstock, this ball is finished with Factory Compound and uses the very responsive HK22C+ Pearl coverstock. These changes make this ball a much better option on medium conditions, whereas the Guru Oracle excelled on heavier oil patterns. The changes to the cover and the box finish make this ball much more skid/flip in shape compared to the earlier, smoother motion of the original Guru Oracle. We really liked the ball, as it allowed us to play multiple angles across our patterns, showcasing its versatility.

Cranker had a large amount of recovery at the breakpoint on the fresh medium oil pattern with the Guru Oracle Pearl. He felt like this ball cleared the front part of the lane very easily, storing tons of energy to make a huge move left when it found the dry. His concerns of seeing some over/under reaction were quickly gone after he missed left and still saw the ball create traction in the midlane. Shots that would leave the bucket or the washout with the Revenge Pearl picked up and dug through the oil easily with the Guru Oracle Pearl. This made it very easy for him to move left at the first sign of the ball over-hooking. When it started to leave the 4 pin, he could move left with confidence, knowing the ball wasn’t going to slide past the breakpoint or
