Hammer Hammerhead Coverstock: Exploring the Power of Aggression Solid Reactive

Hammer Hammerhead Factory Finish: 2000 Siaair for a Balanced Reaction
The Hammer Hammerhead bowling ball comes with a factory finish of 2000 Siaair or 500, 2000 Siaair Micro Pad. This surface preparation is specifically chosen to provide a smooth yet aggressive reaction on medium to heavy oil patterns. The 2000 grit finish strikes a balance, allowing the ball to navigate the front part of the lane without excessive friction while still maintaining enough traction to create a significant hook down lane. This out-of-box finish aims to offer bowlers a versatile starting point, ready for competitive play without immediate surface adjustments.
The 2000 Siaair surface finish on the Hammerhead complements its Aggression Solid reactive coverstock. This combination allows the solid reactive material to effectively grip the lane, generating a strong hook potential and excellent control. The slightly smoother finish provided by the 2000 grit ensures that the ball doesn’t hook too early, preserving energy for a more pronounced and predictable backend reaction. This carefully considered factory finish makes the Hammerhead a reliable option for bowlers seeking a consistent ball motion and substantial hook on its intended lane conditions.
