- Virtual Gravity XRa

First Impressions
The Storm Virtual Gravity XRa presents itself as a standout option in your arsenal for demanding conditions. Built around the Shape-Lock HD core, this ball delivers an extremely stable foundation for heavier oil patterns with a 2.48 RG and a 0.052 differential (intermediate differential: 0.020). The R2X Pearl cover provides outstanding traction in the early phase of the lane. Thanks to the factory 1500-grit polished surface, the ball reads the heads very early and develops consistent rotation through the midlane. Visually it's very attractive, and it immediately signals its focus on heavy oil and maximum control. The combination of the asymmetric design and this strong cover means this ball loses very little energy in the pocket and shows an impressive presence.
Comparison
Compared directly to the Storm Proton Physix, the Virtual Gravity XRa shows a noticeably smoother, more controlled reaction. Where other asymmetric models often react too aggressively to the transition, this ball holds a consistently predictable path. The Storm Proton Physix does offer a bit more length through the first two thirds of the lane, but it lacks the sheer traction the Virtual Gravity XRa builds up in the boards. If you find the Proton Physix too jumpy, you'll find the stability and predictability you need here. It forgives release mistakes better than comparable strong balls, yet still keeps the power to clear the pins extremely effectively. It shows its undeniable strengths especially on changing conditions.
On the Lanes
For practical use on the lane, this ball is best suited to long, high-volume oil patterns. When the heads are oiled up enough, it can show its full potential and delivers a continuous hook toward the pocket. It picks up the friction at the end of the pattern gently but decisively, which leads to outstanding carry. If you throw the ball fast, this is the perfect choice for hitting the pocket safely and repeatably. Should the lane dry up as play goes on and the transition set in, it's a good idea to plan a ball change early, since it could react too soon on dry boards. It's an excellent ball for oily conditions that fully lives up to the demands of modern performance features and should produce high scores consistently.
