The listed price is for the ball only, but drilling services are available for an additional fee. The cost will vary depending on the specific work required, but we will offer it at a price lower than bowling alley rates. 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 listing for a Roto Grip Gremlin from High Sports. Please refer to the outer box in the photo for specifications. We will contact you separately regarding the shipping date. The following is a quote from High Sports. To conquer today's challenging lane conditions, the Roto Grip development team has succeeded in developing an even more groundbreaking ball. "GREMLIN," born from combining and researching a wide variety of cores and coverstocks, the team discovered through further experimentation that increasing the weight block density to "maximum" raises both RG and DIFF values while slightly lowering the mild asymmetric split. As a result, this shape produces an unprecedentedly clean ball performance with an angular motion. In pursuit of an even more aggressive reaction, V-R1 (Versatile-Response - 1st version) Pearl Reactive was born. This material offers a new level of skid and snap that will satisfy any bowler. Gremlin is the latest addition to ROTO GRIP's HP3 series. In the coverstock V-R1, V stands for Versatility and R for the 1st version of Response. With a new formulation, it creates higher versatility and responsiveness than eTrax Plus, reducing the impact of misthrows on the backend reaction. The core is an improved version of Rubicon's Raja core, with a heavier weight block body and flip block, altering the RG and differential to create a new roll pattern. Information from the US suggests a movement similar to Rubicon UC2, but I felt it was similar to the IQ series.
