Product Description
The Motiv Sigma Tour Pearl brings back a legendary name with performance tuned for today’s medium‑oil lane conditions. Built around the proven Sigma symmetric core (2.47 RG, .047 differential in 15 lb), this ball revs up quickly and creates a strong mid‑lane read while still clearing the front part of the lane with ease. Wrapped in the new Atomic Propulsion Pearl Reactive cover and finished at 5000 Grit LSS, Sigma Tour Pearl is clean through the heads, fast‑revving in the midlane, and explosive downlane without becoming over‑responsive or uncontrollable.
Motiv designed Sigma Tour Pearl to fit perfectly between a true benchmark ball and a bigger, more angular pearl, giving competitive bowlers a shape they can rely on when they want to stay aggressive and still keep their angles in check. Compared with earlier Propulsion covers, Atomic Propulsion Pearl offers more traction in oil than the Dark Matter Propulsion shell on Nebula and more pop downlane than the Propulsion MXV covers on Evoke Hysteria and Venom Hysteria, making Sigma Tour Pearl a versatile, high‑performance option for league and tournament play on typical medium‑volume patterns.
