The Hammer Effect Tour bowling ball is unique because it leverages a low RG and low differential asymmetric core design, a concept first pioneered by Hammer with their Obsession and Envy Tour balls. This design, coupled with the upgraded Huntsman Tour core and TourV3 Solid reactive coverstock, results in a ball that offers a predictable, smooth, and continuous motion, ideal for combating medium oil lane conditions.

The Effect Tour features the Huntsman Tour core, an evolution of the original Huntsman core. By removing the Radial Disc from the bottom, the differential and intermediate differential were lowered, creating optimal dynamics for a high-performance tour ball. This core design, inspired by the successful Vibe and Gas Mask cores, ensures a powerful and predictable reaction on the lanes.

The Hammer Effect Tour bowling ball utilizes the TourV3 Solid reactive coverstock. This coverstock provides a strong mid-lane and backend reaction, making it suitable for medium to heavy oil conditions. The V3 cover also allows bowlers to get closer to the dry part of the lane, making it particularly effective for those with higher rev rates.

The Hammer Effect Tour is designed for medium to heavy oil lane conditions. Its TourV3 Solid coverstock and low RG, low differential core provide a strong reaction that can handle moderate amounts of oil while still providing a powerful backend motion.

The RG, differential, and asymmetry values vary depending on the weight of the ball. For a 15-pound ball, the RG is 2.472, the differential is 0.036, and the asymmetry is 0.012. These values contribute to the ball’s predictable motion and strong backend reaction.
