Solid Reactive
Mastermind (modified) Core
The New Modified Mastermind Low RG core features a single density squared-off elliptical inner core. The core is dynamically designed to extend the rotational energy, boosting angular velocity to transfer energy to the pins for increased pin action and higher scores.
