So, while Parallax Effect aesthetics are distinctive, they’re not simply a matter of appeal. Every shape and contour of the core; the unique chemistry of the cover; the color down to the finish is optimized to support its dynamic performance.The Aeroflo Core builds on the classical Storm credence of elegance and simplicity. The ellipsed hole filled with lighter core material constructs a higher RG than what is typically found in most asymmetric balls. The flip block coupled at the bottom ensures high total differential, but without the crucial cuts on the Y-axis, the intermediate differential would be just 0.007! The strategically positioned depressions on the Z-axis 6 3/4” from the pin mimic the effect of an extra hole in a similar space and keeps the intermediate differential at a more workable amount. Having a precise ratio of intermediate to total differential makes drilling less sensitive for drillers and provides a truer roll for bowlers.Coverstock: TractionX7 Pearl ReactiveWeight Block: Aeroflo CoreFactory Finish: 1500 Grit PolishedBall Color: Tangerine/Midnight/TurquoiseFlare Potential: HighFragrance: Orange Coffee CakeWeights: 12-16 lbs This is a brand new in box 1st quality ball and is un-drilled.
