Go for Shock and Awe with the Roto Grip Haywire.
The Middle Roll 70 core has been featured on many Roto Grip balls and delivers a Medium RG/Medium Differential, giving the ball the ability to read the midlane and come back with a great (but controllable) backend.
Wrapped around this core is the 80H MicroBite coverstock featured on the Hyper Cell. Sanded to a 2000-grit finish, this ball bites, grips and charges towards the pins on heavy oil conditions. The electric Navy/Peach/Sky Blue gives a shocking reminder to your opponents as to which ball just destroyed them.
Here's what Roto Grip has to say about the Menace:
My opponents think they can handle the voltage?!?! They’ll realize just how wrong they are as my proven Middle Roll 70 core delivers a midlane charge they’ve never seen and my rough and ready Micro Bite coverstock tears through anything that stands in my path.
