This is a new Storm Virtual Gravity Pro X-3 from High Sports. Please refer to the outer box in the photo for specifications. The following is a quote from High Sports. This is the first in the Virtual series to adopt EXO material. Combined with the powerful "Shape-Lock HD Core," it rolls through the front of the lane while maintaining moderate friction and goes straight. It is easy to predict the breakpoint, and while emphasizing the backend, it is an easy-to-throw product. In terms of axis movement, it precisely carves out flare potential, but with minimal power loss, it creates a continuous, bow-shaped curve. For pin action, it delivers top-class pin carry for STORM, maximizing the features of the "Shape-Lock HD Core." Although it is a strong pearl material, its ease of throwing makes it an optimal ball for everyone from strokers to those who prioritize the backend. It is such a popular product that ENERGY was re-released in the US, and PBA player Kyle won a tournament with this product, reaffirming the excellence of the SHAPE LOCK core. This X-3 uses a pearl EXO that is moderately strong against oil. By emphasizing straightness, it provides a smooth feel, and from the breakpoint, it curves with good angle retention without being too sharp. Its consistent curve makes it easy to adjust your line. EXO Pearl does not feel the oil differential much. It has a high cover rate for misthrows, and even if you throw it too wide, it curves moderately, and if you drop it inside, it skids appropriately, making it easy to hit the pocket.
