The recent focus of high performance bowling ball technology has been based on asymmetry and pushing the limits of physics. Storm Products' has turned the corner with the new Perfect Dimension.The Core At the heart of the Angular Dimension is the all new, technologically advanced Continuum core. By inverting and rotating two identical asymmetric halves 90 degrees, and then merging them together, we have created equal mass displacement.This translates into a tune able break point found in asymmetry with the continuation and finish of symmetry. This high performance ball possesses tremendous versatility and performance to fit a variety of styles and conditions.The Cover Conceived by a company whose vision is relentless and developed for the bowling purist Storm's R2X is clearly the new benchmark of traction performance in oil. The R2X coverstock is a product of continual evolution and refinement which occurs at the highest levels of research and development.This highly durable, solid reactive coverstock continues to deliver from the foul line through the pin deck on a variety of medium to heavy oil patterns with the out of the box 2000 grit Abralon finish. Minor surface adjustments, from dull to polished, will open up endless possibilities for the next Dimension in bowling.Technical SpecsCoverstock R2X Solid ReactiveWeight Block Continuum CoreBall Finish 2000 grit AbralonBall Color BluePurpleGreenDurometer 73 75 Rex D scaleFlare Potential 5 6 HighProduct Type Bowling Balls
