Featuring the proven Effect core wrapped in HK22C² technology, Full Effect fits perfectly between Maximum Effect and Zero Mercy Pearl, offering a unique look that blends power with control. The lower RG allows Full Effect to pick up earlier and roll heavier through the midlane, while the polished cover produces a strong, sweeping backend shape that’s more continuous than the Zero Mercy Pearl. The result is a shiny ball that doesn’t skid past the breakpoint and never misses the spot. With its ability to handle more oil than expected for a polished piece, the Full Effect is one of the strongest shiny pearl balls on the market today, giving bowlers confidence to stay aggressive without sacrificing predictability.
