First Impressions
The Radical Grease Monkey Whack stands out with an extremely bright purple and yellow pearl look. Inside works the symmetrical Grease Monkey core, which features a 2.540 RG and a solid 0.048 differential. For the surface, Radical relies on a pearl reactive cover polished to a high gloss out of the box. These specs should make the ball start up extremely late and skid safely through the heads on dry lanes. The cover and the core offer the perfect mix of maximum length and a late hook.
Comparison
Compared directly with the Radical Grease Monkey Solid, the Whack version shows noticeably longer ball motion, delivers less traction in oil and a much more angular reaction at the breakpoint. Next to the Storm Match Pearl, the Grease Monkey Whack offers a comparably smooth but more flaring hook thanks to its strong differential. When the transition changes the lane and dry spots appear, the smooth surface keeps the ball from overreacting uncontrollably at the breakpoint. It snaps hard.
On the Lanes
The Radical Grease Monkey Whack is most at home on dried-up and medium lane conditions. It's an excellent option if you're looking for a clean and predictable ball motion when the lanes are heavily played. The symmetrical core creates a clear angle at the breakpoint, which builds confidence when playing direct lines. The ball should secure carry through its late entry into the pocket. On very fresh patterns, however, it slides right through.
