The listed price is for the ball only. Drilling services are available for an additional fee. The cost will vary depending on the specific work required, but will be offered at a price lower than that of a bowling center. We can also accommodate difficult tasks such as IT work if you consult with us in advance. We will discuss the layout with a dedicated driller while you send us your measure sheet, so please feel free to ask any questions you may have. This is a new Storm Summit Ascent from High Sports. Please refer to the outer box in the photo for specifications. The following is a quote from High Sports. The ASCENT, released worldwide, is the fourth installment since the first Summit, which first adopted A.I. technology. The high-specific-gravity Centripetal HD weight block provides an early roll from the front to the mid-lane, giving the impression of smooth, unwavering movement (less affected by oil) rather than digging into the lane, and even provides a sense of stopping at the breakpoint. Its continuous roll minimizes power loss, and the strong impact on the pins is such that bowlers with low rev rates can experience a messenger they've never seen before. This product also has excellent ball balance and versatility, making it an easy-to-handle ball for a wide range of bowlers. The A.I. Core Technology, developed to overturn the common sense of the bowling world, provides a stronger pin action even with low-rev balls or bends with no angle to the pocket. The adjustment range of the core power has also been expanded, allowing for more precise inertia values to be set for each ball weight. The Centripetal HD-A.I. Core minimizes power loss with its continuous, strong roll.
