Description (merchant text, shortened)
A Strong, Versatile Asymmetric Hybrid for Heavy Oil
About the Maximum Effect
The Hammer Maximum Effect is the strong, versatile hybrid of the Effect line. It pairs the asymmetric Huntsman Core with the HK22 Cohesion Hybrid coverstock at a sanded finish, delivering big flare with a strong but adaptable read on medium to heavy oil. It reads the midlane firmly while staying versatile across a range of conditions.
The Maximum Effect shares the strong Huntsman asymmetric core with the rest of the Effect line but wraps it in a sanded hybrid cover. The HK22 Cohesion Hybrid blends solid and pearl material, so it reads the midlane strong like a solid while clearing the fronts a touch cleaner, a versatile, hard-driving option for heavy oil.
Understanding the Hammer Huntsman Core and Hammer HK22 Cohesion Hybrid Reactive
Hammer built the Maximum Effect for strong but versatile motion on medium to heavy oil. Specifically, the asymmetric Huntsman Core posts a 2.470 RG, a strong .050 differential, and a .017 intermediate differential for high flare and a defined breakpoint, while the HK22 Cohesion Hybrid cover at a 1500-grit finish reads the midlane strong but clears the fronts cleaner than a solid. As a result, it gives you a strong, versatile asymmetric motion. The per-weight specifications are listed below.
A Strong Asymmetric Core, Shared Across the Effect Line
At the heart of the Maximum Effect is the asymmetric Huntsman Core, shared across the Effect line. At 15 lb it measures a 2.470 RG, a strong .050 differential, and a .017 intermediate differential, a combination that produces high track flare and a defined, asymmetric breakpoint.
Because the Huntsman core is asymmetric, your pro shop can tune the layout to control how early and how strong the Maximum Effect plays. Pairing this strong core with a sanded hybrid cover is what gives the Maximum Effect its strong-but-versatile read.
A Sanded HK22 Cohesion Hybrid for a Strong, Versatile Read
The Maximum Effect wraps that core in Hammer's HK22 Cohesion Hybrid Reactive coverstock at a 1500-grit finish. As a hybrid, the cover blends solid and pearl material, so it reads the midlane strong like a solid but clears the fronts a touch cleaner like a pearl, giving the ball big flare with a versatile motion.
That blend is what makes the Maximum Effect such an adaptable heavy-oil piece: it reads firmly but stays versatile across a range of conditions. Leave it at the 1500-grit box finish for medium to heavy oil, take the surface lower for more traction, or polish it up for more length as the lanes dry.
