Mechanical Asymmetric Core Engineering. The MACE™ core has three major benefits, Ultra Low RG core system to engage the Propel 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.
