The Addaptive ƒ(PR) Solid coverstock is Brunswick's newest innovation in performance enhancing additive chemistry. ƒ(PR) describes our latest formula that combines our new (P) rojection and our new (R) ecovery additives together to create our most aggressive coverstock to date. The Projection additive easily pushes the super aggressive coverstock down lane where the Recovery additive connects with the lane for an extraordinary backend hook motion. Being able to combine multiple additives in a coverstock allows Brunswick to effectively fine tune the length, midlane and backend characteristics of the ball. The new Nexus Rotor core integrates a center stabilizing capsule and two vertical flip claws. The center stabilizing capsule revs quickly to control the midlane. As the axis migrates and the core lays down, the vertical flip claws take over maintaining the rev rate for a strong continuation through the backend and powerful drive through the pins. The Nexxus ƒ(PR) is so strong it extends the limits of our Ball Comparison chart. With its 1500grit Siaair micro pad finish, the Nexxus ƒ(PR) offers our highest hook potential & most continuation of any Brunswick ball to date. With an extraordinary ball motion the Nexxus ƒ(PR) skids through the front, saves axis rotation in the midlane and grabs the backend for unbelievable continuation on medium to heavy oil lane conditions. The Nexxus ƒ(PR) 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.
