Hammer Full Effect High Performance Bowling Ball The Hammer Full Effect is the next step in the Effect line, combining strong midlane traction with the powerful backend motion Hammer fans love. Built with the proven Effect core and wrapped in HK22C² coverstock technology, the Full Effect slots perfectly between the Maximum Effect and Zero Mercy Pearl in the lineup. Its lower RG helps the ball read the lane earlier and create a heavier roll through the midlane, while the polished pearl cover delivers a strong, sweeping backend that is more continuous than the Zero Mercy Pearl. The result is a shiny ball that maintains control at the breakpoint without sacrificing power. Capable of handling more oil than most polished pearl balls, the Full Effect provides a confident blend of strength, continuation, and predictability for bowlers looking to stay aggressive on medium to medium-heavy oil.
