The Addaptive ƒ(PF) solid is Brunswick's newest innovation in performance enhancing additive chemistry. ƒ(PF) describes our latest ƒormula that combines our new (P) rojection and our new (F) riction additives together to create our most aggressive coverstock to date. The projection additive easily pushes the super aggressive coverstock down lane where the friction additive kicks in gripping the backend for unprecedented traction. Being able to combine multiple additives in a coverstock allows Brunswick to effectively fine tune the length, midlane and backend of the ball motion. The new Nexus Rotor core integrates a center stabilizing capsule and two vertical flip claws. The center stabilizing capsule rev's 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 drive through the pins. We did it again！ The Nexus ƒ(PF) is so strong we had to add columns to the Ball Comparison chart and increase our Hook Potential scale to describe this ball. With its 1500grit Siaair micro pad finish, the Nexus ƒ(PF) offers our highest hook potential of any Brunswick ball to date. For an extremely aggressive ball motion the Nexus ƒ(PF) skids through the front, saves axis rotation in the midlane and grabs the backend for strong response to friction. The Nexus ƒ(PF) 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.
