The Brunswick Karma Pearl uses the same core design as the Karma Solid, a modified version of the original Danger Zone core. The removal of the nugget in the center of the core lowered the differential. Changing the cover to a reactive pearl version of PowrKoil 18 increased the length and back end compared to the Karma Solid.

We had the best reaction with this ball on our medium test pattern. Each tester could use their normal delivery on this pattern. Stroker was playing the...

There is very little read of the front part of the lane out of the Karma Pearl. This makes it just as useful on shorter patterns as it does on medium length patterns.
Length
(1-25)

The polished box finish allows the Karma Pearl to match up best with medium oil patterns. Moves slightly deeper into the oil will get the necessary length on drier patterns as well.
Back End
(1-20)
15
Despite being a pearl cover, the Karma Pearl doesn’t cover the most amount of area at the back end. It will be best suited for lanes where a lot of length with a controlled back end reaction is required.
Total Hook
(1-100)

The total hook potential is a couple of boards less than the Karma Solid. This pearl version is weaker both in the oil and back end, allowing it to perform better on drier conditions than the solid.

Strengths: The pearl PowrKoil 18 shell allows players of all styles to use the ball on medium-dry and drier lanes without sacrificing carry. The length of the Karma Pearl makes it a great choice for tournament bowlers to go to late in the blocks.

Weaknesses: Long oil patterns will force the Karma Pearl to slide past the desired breakpoint. Bowlers can see this same reaction on medium patterns as the oil starts to carry down the lane.

Overall Summary: The Karma Pearl features the same core/cover combination as its solid counterpart. This one, combined with the Karma Solid, makes for a suitable one-two combination for medium and dry patterns at an affordable price.
