The S72R™ Coverstock utilizes the same base formulation as the S72™ Coverstock. However, we have added a catalyst that will greatly increase the performance on the backend while also maintaining great traction in the oil. The Amplify™ Core is a new design that features the same shape as the Ellipticon™ Core found in the Continuum™. We have added a flip block to the bottom of the core though. This will increase the differential and maximize torque at the breakpoint.
