The shape of the new Centripetal core allows for consistency of dynamic design after drilling. What this means is that you can drill the Prodigy with a variety of layouts and guarantee consistent, predictable results from break point to pocket. As for the cover, we encased the new core shape with a multitude of options and found the aggressive and reliable R2X™ Pearl material with E.T.M. (Enhanced Traction Mica) gave us the desired results. Having proven itself with the Second Dimension™ as Rhino Page will testify, the R2X Pearl with E.T.M. increased the surface profile as verified with the laboratory-quality profilo-meter. And with a 4000-grit Abralon™ finish, you are sure to get a clean glide through the heads without sacrificing control of the midlane. You’ve got the best of both worlds!
