S84 Response Pearl Coverstock
The S84 Response Cover, with its special chemical composition that creates up to 20% larger pore sizes, has been altered to a 1500-grit polished finish. The Reality, even though it was a cleaner dull ball, is still very strong in the front part of the lane. The Altered Reality will clear the heads much easier and save more energy for the back part of the lane. Even though the cover is a pearl and polished, the larger pore size allows for more traction in the oil than traditional pearl covers.
The S84 Response Pearl Reactive Cover is back with a vengeance. Due to the increased microscopic pore sizes, this cover will be clean through the front part of the lane like a pearl should be, but also dig into the oil whereas other pearl covers tend to struggle with. This is the exact same cover that was used on the Altered Reality. As a matter of fact, 2 of the 3 colors used on the Altered have been utilized on the Eternity as well. As with all of our high performance pearl covers, bowlers will find the Eternity to be easily tunable and able to cover a broad spectrum of oil conditions.
Disturbance Core

The Disturbance Asymmetric Core utilizes a modified scutoid geometric shape. This eccentric shape has a base of 6 sides and an apex of 5 sides. The elimination of the 6th side as you move vertically up the weight block creates the perfect amount of asymmetry. This shape also provides the RG/Diff values that all bowlers demand by utilizing a smaller amount of space within the outer core. When you put all of this together…we have created a truly unique and never before seen reaction to the 900 Series.
