The Activator® Plus coverstock used on the Diamondback Sunrise is a proven formula that provides strong mid and downlane recovery, longevity of ball reaction, and unprecedented durability with superior resistance to cracking. The Diamondback Sunrise uses the proven Brunswick multisided Rocket™ core system. The Rocket core is a Low RG core that aids the Activator® Plus in midlane grip and backend recovery. The Diamondback Sunrise, finished with Brunswick High Gloss Polish, will provide excellent length through the front part of the lane. The core and coverstock strength give the Diamondback Sunrise the potential for a strong, continuous backend reaction with remarkable pin action, on typical medium to mediumoily lane conditions. The Diamondback Sunrise can be drilled using the standard drilling techniques developed for symmetric bowling balls. The unique core shape of each Brunswick 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. The same drilling instructions can be used for 12and 13pound balls. This is because Brunswick uses a generic core shape with an RG diff erential that is close enough to the 1416 pound shape.
