Siege

The Siege unites the new Propel coverstock and the MACE core to produce a ball motion that is both aggressive in the oil and aggressive in the backend. The Siege is your ball when your game needs help battling heavy oil conditions and poor pin action.

Coverstock

Introducing Propel coverstock the next extension in Brunswick coverstock technology. Propel 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 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 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 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 Propel 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 wehn your game needs help battling heavy oil conditions and poor pin action. Sieze the lanes, Conquer the pins, Defeat your opponent!!

Micro Finishing Pads

Micro finishing pads have revolutionized the bowling industry by creating smooth surface finishes that many bowlers would assume are polished with a wax or similar compound. The benefit to the bowler is that these finishes create length similar to balls coated with compound finishes, but are better able to handle today’s thicker oils and carrydown. The Siege is finished with 1000-grit micro pads driven by the new Haus high-speed bowling ball resurfacing machine.

Reaction Characteristics

• Out of the Box: With its 1000-grit micro pad finish, the Siege will provide excellent mid-lane recovery and a strong continuous backend reaction that matches up on medium to oily lane conditions for a wide range of bowling styles.
• If your Siege goes too long: A smooth surface will sometimes cause the ball to go too long before breaking. To get your Siege rolling sooner, dull the surface with a 500-grit micro pad to increase hooking action. To further increase hooking action, use a rougher abrasive to create an earlier reaction.
• If your Siege hooks too early: Smooth your Siege with 2000-grit micro pad to increase length. If more length is needed, smooth the surface to 4000-grit micro pad. If more length is still desired use Brunswick’s Factory Finish High Gloss Polish to increase length to the maximum.
