The Grip is a whole lot of performance and technology, for not a lot of cash. The F64 coverstock comes with a 2,000 grit Abralon box finish to provide plenty of traction on the lane. This shell is easily fine tuneable and can be adjusted to 4,000 Abralon or polised to handle lighter volumes of oil. The asymmetric Double Cross core was specifically chosen for it's low Rg and ability to provide a smooth predictable ball motion. Grip - all the traction you want, with all the control you need!

F64 Reactive AMF uses a numeric rating system designed to differentiate our coverstock strengths. F10 least aggressive - F90 most aggressive.
