Product Description The Storm Lightning Blackout bowling ball throws it back to classic style and performance that long-time fans of Storm can appreciate. Just as the original did, this modernized Lightning carries on the same reputation across length, power, and control. This symmetric design is both easy to drill and roll. The flare potential of the Warp A.I. Core falls under the same rating as the immortal !Q Tour. Medium-low differential cores dont migrate as fast which produce more forgiveness and longer transition zones between skid, hook, and roll. A benchmark core demands a benchmark coverstock. The always dependable ReX Pearl cast in black obsidian pearl provides instant visual feedback and helps the ball stand out on the lane. ReX is renowned for clearing the front part of the lane with an unprecedented movement on the backend. The consistency of this shell through the heads is something to be marveled.Color: Obsidean*Please note that colors may slightly vary from image shownCoverstock: ReX Pearl ReactiveWeight Block: Warp A.I.
