The Storm !Q Tour line of bowling balls is famous in the bowling world and the Storm !Q Tour Ruby will be no exception. This upper-mid performance bowling ball uses the R2S Pearl coverstock that not only looks good but performs. This coverstock allows the ball to get through the front of the lane on a variety of conditions before revving toward the pocket with plenty of pin carry. On the inside, this ball features the C3 Centripetal Control Core that provides a predictable, benchmark shape. This core assists in keeping control of the pocket without giving up hook or power.
