The Addaptive ƒ(P) Pearl coverstock is Brunswick's newest innovation in performance enhancing additive chemistry. ƒ(P) describes our latest ƒormula that combines our new (P)rojection additive with an aggressive reactive coverstock to skid easily down the lane, saving axis rotation for the backend that results in higher entry angles into the pocket and improved ball motion through the pins. Being able to utilize performance enhancing additives in a coverstock allows Brunswick to effectively fine tune the length, midlane and backend characteristics of the ball motion. The new Nexus Arrowhead core features a single density squaredoff elliptical inner core that is dynamically designed to stay on line, enhancing downlane projection. This long and sleek core helps the Nexus™ ƒ(P) preserve revs and ball speed into the backend of the lane which results in increased pin action and higher scores. With its Rough Buff Finish, the Nexus™ ƒ(P) Pearl INT projects easily through the front, storing axis rotation and revolutions in the midlane while gripping the backend for a strong continuous motion that slices through the pins with ease on medium oil lane conditions. The Nexus™ ƒ(P) Pearl INT can be drilled using the standard drilling techniques developed for asymmetric 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 RGdifferential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
