TheOuter Limits Pearlis a pearl version of the original released last season. The Outer Limits provided a controlled yet very continuous motion at the backend of the lane and matches up best on medium to oily lane conditions. By adding pearl to our already great HK22 resin, bowlers will see more skid through the front part of the lane and a much stronger and quicker change of direction at the breakpoint. The RG of 2.499, differential of 0.051, and a lower intermediate differential of 0.014 make theOuter Limits Pearl a versatile asymmetrical ball usable on a wide range of patterns.
