Manufacturer's Intent: With 80% of leagues and weekend tournaments played on oil patterns between 39 and 44 feet (Doug Dukes, VP of Sales, Kegel), the Storm EquinoX is purpose-built for league bowlers. Designed for these conditions, it delivers the signature backend motion Storm is known for—combining powerful reaction with consistent performance. The EquinoX is the ideal choice for bowlers looking to dominate their league nights and weekend tournaments with confidence and precision.

With the stronger asymmetric shape, I chose to use my standard pin up layout on the new Storm Equinox. Stronger asymmetric cores create lots of track flare and a very strong rolling core motion, so I don't really need help getting this ball going down lane. I left the Equinox alone and threw it with the box surface as well. I've had a lot of success with the Power Edge polished balls so far, and Equinox extends that streak. This one rolls extremely well but is very different than the typical Storm reaction. The manufacturer's intent mentioned that they wanted to specifically design a ball for league bowling, and I believe they've done just that.

The thing that stood out to me about the Equinox is that it isn't necessarily super long down the lane. Equinox rolls up in the late mid-lane on standard league patterns, making the ball more suitable to hit the pocket more often. Many times, our customers look for balls that are super long and angular down lane. That doesn't always benefit them as much as they'd like. Most times it's far better to have a ball that will roll up a touch sooner but still go through the pins well. That's exactly what Storm designed in the new Equinox. Equinox is definitely earlier rolling than balls like Attention Star and Virtual Energy Blackout, but it's also a little less backend as well. Smoother with continuous arc is what I see from the Equinox. All of this combines to ball perfectly suited for easier league conditions.

Much of this control with continuation seems to come from the new Solarian A.I. core shape. Traction in oil is usually created from the cover and finish, but ball shape and motion are determined by core shapes. This new core shape gives Storm something very unique from their previous products, and the Equinox should be a welcome addition for Storm league bowlers. Combined with their new A1S Pearl cover, Storm seems positioned to open up a new window in ball performance that they haven't gone to in a while.

Storm Equinox will be in stock at TBG on February 7th!
