The Torque Choice

Hardened features an asymmetrical core. We wanted to create a torque option that would read the late mid-lane while featuring more angle and overall hook on the backend (compared to the classic choice, Failsafe).

This ball will have a very familiar motion for those players who love asymmetrical ball motion.  Hardened reads in the late-midlane while providing a continuous, strong motion through the pins.

Due to the lower intermediate differential, Hardened does not roll as forward off of the breakpoint as most asymmetrical balls on the market. The continuation off of the breakpoint is important to create carry for this choice.

Hardened stars a royal purple and lime green color scheme which announces that this ball is ready to take on the majority of lane conditions.

* Coverstock Strength

The coverstock strength number is an incorporation of our internal testing and some external testing done by the USBC and others. Most coverstocks will be between five and nine, however WorXshop may try using a super aggressive coverstocks or urethane covers in the future.

** Core Strength

The core strength is a number developed from our own internal core ratings system that has developed since Paul’s days at the United States Bowling Congress. It takes into account a multitude of things into the number. Most symmetrical cores will not go above a 20 out of 25, while most will be around eight to 14, while asymmetrical cores will be between 14 and 25. We may even try and reach a score of 28.

What does a high core strength number mean? A high core strength number, paired with the right coverstock will improve carry through the pocket, have a sharper breakpoint, and will maintain its path more through the pocket.

+ Versatility Index

The versatility index is a measure of how much you change the total differentials in a bowling ball with the weakest drilling we would recommend in the ball and the strongest layout. This is a range of how tunable that particular choice will be out of the box.
