Brunswick Karma Solid

46 Hook 15 Length 14.5 Breakpoint Shape

Core Design: The light-bulb symmetric core found in the original Danger Zone (1996) returns with tweaks. The RG is medium at 2.53 while the .040 Diff produces 5” of track flare with stronger layouts. The original core’s bismuth nugget has been removed to comply with new USBC standards.

Coverstock: Supplying the necessary lane traction is a solid reactive version of the PowrKoil 18 family of coverstocks. Colors are a conservative blending of dark blues and black. The surface is 500-sanded, then rough buffed and, lastly, high gloss polished. Response time off drier boards is moderately quick and oil traction is limited.

Manufacturer’s Intent: “Our intent for the Karma Black Blue Solid was to bring back the Danger Zone reaction to our affordable performance price point,” said Bill Orlikowski, Brunswick Product Manager.

Test Results: The Karma core/cover combo provides early core lope, with most of the revving action occurring near the breakpoint. The old-school design still matches up well for a multitude of bowler styles and speed-to-rev ratios. Strokers can play more direct lines with a slower response off the friction areas. Power players will love the ease of length and urethane-like control downlane. The Karma will bridge the gap between urethanes and Brunswick’s Anaconda or Damage pearl reactives. It will react slightly stronger than the Avalanche line that it replaces thanks to the higher differential (track flare) offered by the Danger Zone core shape. That ball ruled in the late ‘90s when it was in a class by itself. In today’s highly competitive marketplace, the Karma will be a key player for those trying to keep total hook manageable in higher-friction environments.

When to Use: The Karma Solid will offer controllability with above-average longevity for light to medium oil volumes, contingent on the bowler’s release power. Low to medium rev rates will find many uses near the lanes’ friction areas with little chance of an over-read or early hook. Higher rev rates can use angles slightly deeper inside the oil line and still see ample downlane recovery.
