Motiv Sigma Tour Pearl

Some sequels are worth the wait. Back in 2011, the Sigma Tour became one of those balls bowlers never stopped talking about. Fifteen years later, the legend comes back stronger. Meet the Sigma Tour Pearl, a weapon built for modern lane conditions. Fast revving, clean through the fronts, and explosive down lane without becoming uncontrollable. It fits perfectly between your benchmark piece and your big angular pearl. Over the past year, Motiv has reinvented what our pearl coverstocks can do with the Evoke Hysteria, Venom Hysteria, and Nebula changing perceptions and turning the heads of so many bowlers. The Sigma Tour Pearl takes that evolution even further with the proven Sigma core, proven Propulsion technology, and a shape every competitive bowler needs. The Propulsion cover line has become the standard for clean and angular motion. The Propulsion covers found on the Evoke Hysteria, Venom Hysteria, and Nebula are angular, versatile, and reliable for casual to competitive bowlers. The Sigma Tour Pearl features the new Atomic Propulsion™ Pearl Reactive coverstock. This new cover gives bowlers more traction in oil than the Dark Matter Propulsion cover on the Nebula, while creating more down lane motion than the Propulsion MXV covers found on the Evoke Hysteria and Venom Hysteria. Atomic Propulsion creates a shape that lets you stay aggressive without losing control.
