Radical’s new Grease Monkey Whack is the third entry into the Monkey family. This is the second time a reactive hybrid coverstock will encase the Grease Monkey core design that has remained unaltered in this version. This cover is stronger both in the oil and at the back end than the first Grease Monkey.

We liked the Whack on our medium test pattern. All three of our testers were able to start a few boards left on both the approach and with their eyes from where they usually have the most success on this pattern. The Whack still created enough traction in the oil on the shots we missed left to keep it from squirting at the breakpoint. We also had miss room right, as the Whack’s polished cover got it far
