By definition, a benchmark is a standard against which you compare other similar things. In bowling, a benchmark reaction usually entails a medium hook and a medium amount of angularity at the breakpoint. A benchmark reaction also tends to be fairly versatile and can be manipulated easily by bowlers who can adjust speed, axis rotation, and/or loft.
- Benchmark balls tend to have symmetrical cores with lower RGs and medium to strong differentials.
- Often, benchmark reactions are created by solid reactive coverstocks that provide predictable motion and strong continuation downlane.
Some bowlers will have a benchmark ball with different attributes, such as an asymmetrical core and/or a hybrid coverstock. Regardless of the exact ball, the goal is to have a reaction that helps you see the lanes well and provides versatility. The benchmark ball is often the first one out of your bag.
