About the Equinox Hybrid
The Equinox line has given Storm bowlers two clear options for a few years now. The original Equinox paired the Solarion A.I. Core with an A1S pearl cover for length and a defined move off the end of the pattern. The Equinox Solid put an A2S solid cover on that same core for early traction on heavier oil. Bowlers kept asking for the piece in between, and that is exactly what the Storm Equinox Hybrid is.
Storm calls this the most balanced Equinox to date, and the build backs it up. The same tri-cylindrical Solarion A.I. Core sits under the second generation of Storm’s Adhesion System, A2S Hybrid Reactive, finished at Power Edge. The solid and pearl components of that cover work together: enough traction to read the oil without burning up, then the clean, recognizable Storm shape at the back. The Nebula, Flare and Void color combination is one of the better looking balls Storm has released, and the Orange Creamsicle fragrance is the finishing touch.
Understanding the Storm Solarion AI Core and Storm A2S Hybrid Reactive
The Equinox Hybrid is a high performance asymmetric built for medium to heavy oil. The Solarion A.I. Core measures RG 2.48 with a .054 differential and a .018 PSA at 15 lb, so it revs up early and flares hard, and its tri-cylindrical shape changes the ball’s dynamic properties as it travels down the lane. That is what keeps it from over-skidding while still holding energy for the finish. The A2S Hybrid cover at a Power Edge finish handles the front part of the equation: it grips the oil without checking up too soon. The numbers by weight are listed below.
The Tri-Cylindrical Asymmetric That Changes As It Travels
The Solarion A.I. Core is the same weight block that drove both previous Equinox releases, and it is the reason the line reacts the way it does. At 15 lb it measures a 2.48 RG with a .054 differential and a .018 PSA, numbers that put it firmly in the strong, high flare category. It revs early, it flares hard, and it gives you a defined transition rather than a gradual arc.
What separates it from a conventional asymmetric is the tri-cylindrical shape. As the ball travels down the lane, that geometry actually shifts the core’s dynamic properties, so the ball resists over-skidding through the fronts while still holding enough energy for a strong finish. In practice that means you can play it in oil without watching it die at the breakpoint.
Storm’s Second Generation Adhesion System, Now in Hybrid
The A2S Hybrid Reactive cover is the piece that makes this the most balanced ball in the family. A2S is the second version of Storm’s patented Adhesion System, and it pushes oil absorption rates to the limit while creating a tackier than normal feel on the lane surface. In hybrid form, the solid and pearl components split the work: the solid side supplies traction in the oil, the pearl side keeps the ball from checking up early and preserves the backend.
Out of the box it runs Storm’s Power Edge finish. That is a polished look with real bite underneath, which is why the Equinox Hybrid reads the midlane without the abrupt shape a dull solid gives you on the same core.

Who This Ball Is Right For
Good to Know Before You Buy
Where It Fits in Your Arsenal
The Equinox Hybrid is the balanced high performance piece in the middle of a Storm bag. It is stronger and earlier than a pearl asymmetric, and cleaner through the fronts than a dull solid on the same core. If you already own the Equinox or the Equinox Solid, this is the ball that fills the gap between them rather than duplicating either one.
Surface Adjustments
Power Edge is a strong out of box setup for medium to heavy oil. Dulling the surface moves the reaction earlier for heavier volume, and refreshing the polish restores length when the lanes break down. Have surface changes done at your pro shop so the finish stays even.
Coverstock Care
The A2S Adhesion System pushes oil absorption to the limit, which is part of why the ball grips the way it does. That also means it takes on oil faster than a milder cover, so wiping it down between shots and deep cleaning it regularly is what keeps the reaction consistent over the life of the ball.
