The new Honor Roll Solid reactive coverstock is Brunswick’s latest cutting edge development based off our performance enhancing additive chemistry technology. Honor Roll Solid coverstock offers the most aggressive coverstock to date for a Brunswick ball. This aggressive coverstock produces easy length through the heads with unsurpassed traction in the mid-lane and backend to achieve ultimate hook. The Mastermind Ultra Low RG core features a single density squared-off elliptical inner core. The core is dynamically designed to extend the rotational energy, boosting angular velocity to transfer energy to the pins for increased pin action and higher scores. The new Mastermind breaks through the hook barrier again extending the overall hook potential range for the Brunswick product line.. The Mastermind with its 1500 grit Siaair Micro Pad finish, reaches the highest hook potential of any previous Brunswick ball to date on medium to heavily oiled lane conditions. The Mastermind can be drilled using the standard drilling techniques developed for asymmetric core bowling balls. At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
