It pairs the asymmetric Criterion I.D. Core with the Super Response Pearl (HK22C) coverstock at a polished finish, delivering a cleaner, more controlled motion that blends wet and dry patterns better than a traditional asymmetric. It is a smart choice for medium oil where both strength and control matter.\n\nThe Criterion Inverse takes an asymmetric core and gives it a forgiving, controlled personality. The Criterion I.D. core provides a defined breakpoint and flare, while the polished HK22C pearl gets the ball down the lane cleanly and reads the friction smoothly rather than jerking. The result is an asymmetric you can trust to blend the lane and finish predictably.\n\nUnderstanding the Track Criterion I.D. Core and Track Super Response Pearl (HK22C)\n\nTrack built the Criterion Inverse for a controlled, blended asymmetric motion on medium oil. Specifically, the asymmetric Criterion I.D. Core posts a 2.50 RG, a .047 differential, and a .016 intermediate differential for a defined breakpoint, while the Super Response Pearl HK22C cover at a polished finish reads the friction cleanly and smoothly. As a result, it gives you a controlled, predictable asymmetric shape that blends wet and dry. The per-weight specifications are listed below.\n\nAn Asymmetric Core Tuned for Control\n\nAt the heart of the Criterion Inverse is the asymmetric Criterion I.D. Core. At 15 lb it measures a 2.50 RG, a .047 differential, and a .016 intermediate differential, a combination that produces a defined, asymmetric breakpoint with controllable flare. The numbers give it shape without an overly sharp or hard-to-read reaction.\n\nTrack wraps the Criterion I.D. core in DynamiCore, Brunswick's industry-leading outer-core technology, for added durability and a stronger hitting ball. Because the core is asymmetric, your pro shop can tune the layout to control how clean and how controlled the Criterion Inverse plays.\n\nA Polished HK22C Pearl That Blends Wet and Dry\n\nThe Criterion Inverse wraps that core in Track's Super Response Pearl (HK22C) coverstock at a polished factory-compound finish. The pearl additive and polished surface let the ball get down the lane cleanly and read the friction smoothly, so it blends wet and dry patterns better than a traditional, harder-snapping asymmetric.\n\nThat cleaner, more controlled motion is the Criterion Inverse's signature: it gives you asymmetric shape and flare without an unpredictable backend, which is exactly what you want on a transitioning medium-oil pattern. Leave it polished for a controlled, blended read, or take the surface down at your pro shop for an earlier, stronger reaction on more oil.\n\nCriterion Inverse Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Tournament Players: A controlled asymmetric pearl that blends wet and dry patterns on medium oil\n\n✓Control Players: Asymmetric shape and flare without an overly sharp or unpredictable backend\n\n✓Tweener and Stroker Styles: A clean, smooth-reading pearl that holds its line and finishes predictably\n\n✓Arsenal Builders: The blended, controllable asymmetric piece for transitioning medium-oil patterns\n\nGood to Know Before You Buy\n\n·Ships polished: The 1500 Grit Polish finish runs clean and long out of the box. For an earlier read on heavier oil, take the surface down at your pro shop.\n\n·Asymmetric layout sensitivity: Layout choices shift the reaction more than on a symmetric ball. Match the pin and mass bias to your game with your pro shop.\n\n·Colors vary: Actual colors vary somewhat from the photos shown; no two balls come out of the mold exactly alike.\n\n·Tiny pit holes are normal: A few tiny pit holes in the coverstock are a normal part of the manufacturing process.\n\n·Sold undrilled: Ships without finger holes, so it can be fitted to your hand and span.\n\nBowlersMart Tips: Where the Criterion Inverse Fits in Your Track Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Track lineup, the Criterion Inverse is the controlled, blended asymmetric pearl. It reads cleaner and smoother than the stronger Synthesis and Paragon pieces, so it shines on medium oil and transition where control matters as much as strength. Pair it below your strong solids as the lane breaks down.\n\nSurface Adjustments\n\nThe polished finish gives the Criterion Inverse its clean, controlled read. Take the surface down with a lower-grit pad for an earlier, stronger reaction on more oil, or keep it polished for a blended, controllable look. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the HK22C pearl cover with an approved reactive ball cleaner after every session, and deep clean it periodically. Keeping the cover fresh preserves the clean, controlled read that defines the Criterion Inverse.\n\nEarn points on every Track purchase through the Striking Rewards loyalty program.
