In sports we are always told to hustle well now Roto Grip is providing a ball that will do just that on the lanes. The Roto Grip Hustle PBR was designed to variety to the Hustle line of bowling balls. This ball takes a medium RG core and low differential to create a ball that will offer more control down lane. The VTC-S20 Solid Coverstock was created to offer a slightly different reaction. This Versatile Traction Control coverstock along with the 3000 grit finish was designed to react early without starting to roll too early on light oil lanes.
