The Ebonite Spartan Pearl is the follow-up to the solid-covered Spartan from the start of the year. Both balls share the Iron Fist V2 asymmetrical core shape, with the differences coming from the coverstock and the box finish.

This combination allows the Spartan Pearl to clear the front much better and be much more angular at the breakpoint compared to the original. We liked this ball on our medium oil pattern, and we were also able to use the length it provided to get to the pocket on the dry test condition.

The ball was even more angular off the spot than the Entity Pearl and The One Ovation, both of which were no slouches at the breakpoint. He had enough traction through the oil from the aggressive pearl cover to keep the ball from over-skidding and having too much length on shots that were missed inside of target. This allowed him to move left quickly when the ball started to over-hook. He could
