At first glance the Centripetal HD Core may look familiar, but deep down is where the magic truly happens. It is the densest core of any Storm ball to date producing an RG value of 2.47. Because the Centripetal HD Core’s center of gravity is extremely low, it consistently impacts the pins at the perfect spot every time maximizing carry.
