Activator® Plus is a more aggressive version of the original Activator® coverstock formulation and features enhanced durability and performance longevity. The pearlized version of Activator® Plus coverstock used on the Massive Damage is factoryfinished with rough buff compound to create more traction in the oil, increasing the ball's midlane and backend hooking action, while still being clean through the front part of the lane. The Massive Damage uses a larger pearl additive that creates more vivid colors and provides added length and backend reaction. The Massive Damage features a new Low RG Performance core that revs quickly providing midlane control with a strong predictable backend motion. With its Rough Buff finish, the Massive Damage will rev quickly in the midlane with a strong continuous backend reaction that matches up on medium oil lane conditions for a wide range of bowling styles. The Massive Damage can be drilled using the standard drilling techniques developed for symmetric 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.
