The Hammer Maximum Effect uses the same asymmetrical Huntsman core design that was previously found in the Effect and Special Effect. This low RG (2.470″), medium-high differential (0.050″), and high intermediate differential (0.017″) design revs up quickly and provides plenty of flare potential. The Maximum Effect combines a very aggressive coverstock with this weight block. The HK22 – Cohesion Hybrid CFI cover comes out of the box at a rough 500/1500 SiaAir finish. This aggressive cover and dull box finish create tons of traction, while the large-flaring core allows fresh surface to see the lane as it makes its way to the pocket. We saw tons of total hook from this ball, and it required all three of our bowlers to start farther left than usual. The more oil that was on the lane, the better the reaction was for the Maximum Effect for all three of our testers.

Stroker threw his first shot with the Maximum Effect on the heavy oil pattern and almost missed the headpin to the left. The ball picked up quickly and still made a big move downlane. He ended up farther left with his laydown point than he was with both the 3-D Offset Assault and the Pure Envy. He needed to make sure to swing the ball, and as long as he did, he couldn’t miss on this pattern.
