The Storm Equinox Solid marks the return of the unmatched Solarion A.I. Core, now paired with the next evolution of Storm's Adhesion System technology, the A2S Solid coverstock. If you are chasing total hook, the Equinox Solid stands toe-to-toe with the Ion Max, but with a dramatically different shape and motion.\n\nThe Equinox Solid pairs that asymmetric Solarion A.I. Core with the A2S Solid Reactive cover at a 2000-grit finish. The low-RG tri-cylindrical core revs hard and the sanded solid cover digs into the oil early, so where the original Equinox skids and flips, the Solid reads earlier and hooks more, bold, aggressive, and built to stand out on heavier volume.\n\nUnderstanding the Storm Solarion A.I. Core and Storm A2S Solid Reactive\n\nStorm built the Equinox Solid for total hook with a distinct shape. Specifically, the asymmetric tri-cylindrical Solarion A.I. Core lowers RG for fast revving and a tumbling read, while the A2S Solid cover at a 2000-grit finish grabs the front and mid-lane early for maximum traction. As a result, it reads earlier and hooks harder than the pearl Equinox, delivering strong, continuous motion that rivals the Ion Max with a different look. The full per-weight specifications are listed below.\n\nA Tri-Cylindrical Asymmetric Core Built to Rev and Drive\n\nAt the heart of the Equinox Solid is the asymmetric, tri-cylindrical Solarion A.I. Core. At 15 lb it measures RG 2.48, a strong .054 differential, and a .018 intermediate differential (mass bias), numbers that produce heavy flare and a strong, decisive motion. The three distinct cylinders each do a job: the largest lowers RG for fast revving and a tumbling front-lane read, the top cylinder enhances drilling versatility, and the lightweight base adds torque and continuation.\n\nOn the Solid, that revving core is paired with an aggressive sanded cover, so the classic Solarion skid-flip is dialed toward earlier read and total hook. The strong differential supplies heavy flare for heavier volume, while the asymmetric shape drives hard and continuously through the pins. Because it is asymmetric, layout has a strong influence on the reaction, so your pro shop can tune the pin and mass bias to your game.\n\nAn Aggressive Solid Cover for Early Read and Total Hook\n\nThe Equinox Solid wraps that core in Storm's A2S Solid Reactive coverstock, the next evolution of Storm's Adhesion System technology, at a 2000-grit finish. The sanded solid cover grabs the front and mid-lane early and hard, delivering the traction needed for heavier volume, then drives continuously through the pins, the engine behind the Solid's total-hook reputation.\n\nThat strong, early read is exactly what separates the Solid from the pearl Equinox. Where the pearl skids and flips, the A2S Solid reads sooner and hooks more, standing toe-to-toe with the Ion Max on hook while delivering a different, more controllable shape. Leave it at the 2000-grit box surface for maximum traction, or polish it up at your pro shop for a cleaner, longer read when the volume drops.\n\nEquinox Solid Specs\n\nRG and differential vary by weight. Specifications provided by the manufacturer.\n\nWho This Ball Is Right For\n\n✓Tournament Players: Total hook with a distinct, controllable shape, a strong early-reading solid for heavier volume\n\n✓Higher-Rev Bowlers: The low-RG Solarion core revs hard and the sanded cover digs in for maximum, continuous traction\n\n✓Heavy-Oil Stylists: Ion Max-level hook with a different motion, for bowlers who want strength and a unique look\n\n✓Arsenal Builders: The solid, early-reading side of the Solarion core, paired with the pearl Equinox for length\n\nGood to Know Before You Buy\n\n·Strong, aggressive motion: This is a high-flare piece built for traction. If you want a controlled, lower-hook reaction, a lower-differential ball will suit you better.\n\n·Ships sanded for traction: The 2000 Grit finish is built to grip in oil. Polish it for more length when the volume drops.\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 Equinox Solid Fits in Your Storm Arsenal\n\nWhere It Fits in Your Arsenal\n\nIn the Storm lineup, the Equinox Solid is the strong, early-reading solid on the Solarion core. Where the pearl Equinox skids and flips on medium oil, the Solid reads earlier and hooks more for heavier volume, rivaling the Ion Max with a different shape. It sits high in the bag for fresher, oilier patterns and pairs naturally with the pearl Equinox as the lanes transition.\n\nSurface Adjustments\n\nThe 2000-grit finish is built for early read and maximum traction. Take it even lower for more bite, or polish it up for a cleaner, longer read when the volume drops. Have surface changes done at your pro shop for an even, consistent finish.\n\nCoverstock Care\n\nWipe the A2S Solid cover with an approved reactive ball cleaner after every session, and deep clean it periodically. A strong solid at a low grit absorbs oil quickly, so keeping it clean preserves the aggressive traction that defines the Equinox Solid.\n\nEarn points on every Storm purchase through the Striking Rewards loyalty program.
