- Description: Coverstock: Introducing Recoil™ coverstock the next extension in Brunswick coverstock technology. Recoil is a 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 Recoil coverstock was discovered through testing of new formulation additives and process changes in coverstock manufacturing. Core: M.A.C.E. – Mechanical Asymmetric Core Engineering. The MACE™ core has three major benefits, Ultra Low RG core system to engage the Recoil coverstock, High RG differential to aid in traction through heavy oil and High RG asymmetric differential to quicken the response time to friction. Designed as a two component elliptical core system, the MACE core is dynamically the strongest asymmetric core ever produced for a Brunswick ball. Ball Motion: The Siege™ unites the new Recoil coverstock and the MACE core to produce a ball motion that is both aggressive in the oil and aggressive on the backend. The Siege is your ball when your game needs help battling heavy oil conditions and poor pin action. Seize the lanes, Conquer the pins, Defeat your opponent!!
