The Optimum-Flip Solid coverstock is Brunswick’s newest innovation in performance enhancing additive chemistry. Optimum-Flip is a new coverstock that preserves more axis rotation, more rev rate and more ball speed for the backend to generate the highest Angular Velocity potential of any Brunswick coverstock to date. The new Optimum-Flip Solid coverstock incorporates a new base reactive along with our additive technology to create an outstanding Skid Flip ball motion for the Brunswick product line.

The Aura begins a new age of ball motion for Brunswick never seen before. Outstanding length, super quick response to friction with the most continuation on the backend of any previous Brunswick ball. The Aura with its Rough Buff finish, maintains the highest amount of Angular Velocity at the breakpoint when compared to other previous balls on medium to heavy oil lane conditions. The new Brunswick Aura is designed to fit in between The Nexxxus f(P+S) and the Nexxus Solid f(P+R). This will be a great new addition to the Brunswick line when matching up a ball on medium-heavy oiled patterns.

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.
