Propel X reactive coverstock, the newest addition in Brunswick
coverstock technology. Propel X features an enhanced pore structure to
provide Xtra consistency from shot to shot and Xtra versatility on a

Mechanical Asymmetric Core Engineering. The MACE
medium RG core has three major benefits, medium RG core system for a
breakpoint further down lane, high RG differential to increase backend
traction and high RG asymmetric differential to quicken the response
time to friction.
The Wicked Siege combines the new Propel X coverstock and the MACE
medium RG core to produce a ball motion that is clean through the
front, consistent in the mid-lane with a quick response to friction on
the backend. With its consistency from shot to shot and versatility
across the lane, the Wicked Siege will be the first ball out of your bag
and a new benchmark ball for Brunswick on medium to oily lane
The Wicked Siege can be drilled using the standard drilling techniques developed for asymmetric bowling balls.
