The Evil Siege unites the new Propel Pearl coverstock and the proven MACE core to produce a ball motion that is strong in the mid-lane and aggressive on the backend. The Evil Siege is the ball when your game needs help battling medium to oily conditions and poor pin action.
Propel Pearl Coverstock
Introducing Propel Pearl coverstock, the next extension in Brunswick coverstock technology. Propel Pearl is an evolutionary coverstock developed by Brunswick to improve the mid-lane and backend traction of the ball on today’s slicker oils and lane surfaces. The Propel Pearl coverstock was discovered through testing of new formulation additives and process changes in coverstock manufacturing.
MACE Medium RG Core
Mechanical Asymmetric Core Engineering. The MACE medium RG core has three major benefits, medium RG core system for a breakpoint further down lane, high RG differential to increase backend traction and high RG asymmetric differential to quicken the response time to friction.
