Activator® Plus is a more aggressive version of the original Activator® coverstock formulation that maintains the durability and longevity of ball reaction that are characteristic of the Activator® coverstock family. The roughbuff, pearlized version of Activator® Plus coverstock used on the Maxxx Zone Evolution creates more traction in the oil, increasing the ball's midlane and backend hooking action, while still being clean through the front end. The Maxxx Zone Evolution uses an updated version of the Original Inferno core. Ultra Low RG symmetric core systems rev quickly providing midlane traction control with a strong predictable backend motion. With its 1000 Grit Siaair Micro Pad finish, the Maxxx Zone Evolution will rev quickly in the midlane with a strong continuous backend reaction that matches up on mediumoily to oily lane conditions for a wide range of bowling styles. The Maxxx Zone Evolution can be drilled using the standard drilling techniques developed for symmetric bowling balls.
