Hammer Effect Tour Bowling Ball

A Lower-Differential, Tour-Tuned Effect

About the Effect Tour

The Hammer Effect Tour is the controllable, tour-tuned member of the Effect line. It pairs the asymmetric Huntsman Tour Core with the TourV3 Solid coverstock, delivering the Effect’s defined shape with a lower differential for a smoother, more controllable read on medium to heavy oil. It is built for the precision the best players demand.

The Effect Tour takes the Effect design and tunes it for control. The lower-differential Huntsman Tour version of the core produces less flare and a more even, predictable motion, while the TourV3 Solid cover reads the midlane cleanly. The result is a controllable, tour-style Effect for bowlers who want shape without an overly strong backend.

Understanding the Hammer Huntsman Tour Core and Hammer TourV3 Solid Reactive

Hammer built the Effect Tour for a controllable, tour-tuned read on medium to heavy oil. Specifically, the asymmetric Huntsman Tour Core posts a 2.472 RG, a .036 differential, and a .012 intermediate differential, numbers that produce moderate flare and a smooth, defined breakpoint, while the TourV3 Solid cover at a 1500-grit finish reads the midlane cleanly. As a result, it gives you the Effect’s shape with a more controllable motion. The per-weight specifications are listed below.

A Lower-Differential, Tour-Tuned Version of the Huntsman Core

At the heart of the Effect Tour is the asymmetric Huntsman Tour Core, a lower-differential, tour-tuned version of the Huntsman block. At 15 lb it measures a 2.472 RG, a .036 differential, and a .012 intermediate differential, a combination that produces moderate flare and a smooth, defined breakpoint. The lower differential is what separates it from the standard Huntsman: less flare and a more controllable, even motion.

Because the core is asymmetric, layout has a strong influence on the reaction, so your pro shop can tune the pin and intermediate differential to your game. That tour-tuned control is exactly what advanced players look for in a benchmark asymmetric.

A Controllable Solid Cover for a Clean, Even Read

The Effect Tour wraps that core in Hammer’s TourV3 Solid Reactive coverstock at a 1500-grit finish. The TourV3 solid reads the midlane evenly and controllably, so the ball gets down the lane and makes a predictable, defined move rather than a sharp or early reaction.

That clean, controllable read paired with the low-differential core is what gives the Effect Tour its tour-style precision: shape and traction without an overly strong backend. Leave it at the 1500-grit box finish for a controllable read, take the surface lower for more traction, or polish it up for more length when the lanes dry.
