The Propel Pearl coverstock was discovered through testing of new formulation additives and process changes in coverstock manufacturing. MACE Core: Mechanical Asymmetric Core Engineering. The MACE core has three major benefits: ultra-low RG core system to engage the Propel Pearl 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 Evil Siege unites the Propel Pearl coverstock and the proven MACE core to produce a ball motion that is strong in the mid-land 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. Reaction Setup: The Evil Siege can be drilled using the standard drilling techniques developed for asymmetric bowling balls. Lightweight Engineering: The unique core shape of each Brunswick ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across the weight range. The same drilling instructions can be used for 12- and 13-pound balls. This is because Brunswick uses a generic core shape with an RG difference that is close enough to the 14-16 pound shape.
