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.
