Propel is aevolutionary coverstock developed by Brunswick to improve the mid-lane and backend traction of the ball on todaysslicker oils and lane surfaces. The Propel coverstock was discovered through testing of new formulation additives andprocess changes in coverstock manufacturing.Core: M.A.C.E. Mechanical Asymmetric Core Engineering. The MACE core has three major benefits, UltraLow RG core system to engage the Propel coverstock, High RG differential to aid in traction through heavy oil andHigh RG asymmetric differential to quicken the response time to friction. Designed as a two component elliptical coresystem, the MACE core is dynamically the strongest asymmetric core ever produced for a Brunswick ball.Ball Motion: The Siege unites the new Propel coverstock and the MACE core to produce a ball motion that isboth aggressive in the oil and aggressive on the b
