The Turmoil HFS solid cover found 12 years ago on the original Covert Revolt was a favorite.  But the game has evolved.  Oil has gotten heavier and thicker leaving the original cover in need of an upgrade.  The new Leverage HFS Solid cover offers the same length and control as the Turmoil HFS cover, but with added strength for modern oil conditions.   When paired with the Vanquish core, this cover provides enough length through the front of the lane with plenty of traction in the mid-lane for a smooth and controllable ball motion and nonstop drive through the pins.   

Featuring the Vanquish Symmetrical core originally featured in the Revolt line in weights 16#-14#, this powerhouse produces an explosive 2.47 RG to increase rev potential and .056 differential for aggressive track flare.  This combination delivers unstoppable strength and control.  In 13#-12#, the symmetrical Quadfire™ core is featured for fantastic specs, even at the lower weight.
