Please refer to the outer box in the photo for specifications. The following is a quote from Hi-Sports. The 7th installment of the popular PHAZE series, <Phase Star>, boasts the most straight-line performance in the series. The combination of the moderate rolling feel of the internal [Velocity Core] and Storm's representative benchmark coverstock, R2 material, creates strong skid and a reassuring roll from the mid-lane. Among pearl coverstock products, it is the least erratic at the backend, and the pin hit from a strong arc is powerful, as if it's knocking down pins with force. It has more straight-line performance than the first generation, making it an ideal finish for the latter half of tournaments and medium-dry conditions. Recent PHAZE series products have tended to be strong against oil. In the Master Line products, the Centripetal Core rolls from an early stage, and the coverstock creates a strong arc, while the [Velocity Core] increases its roll from the mid-lane, and this rolling continuity at the backend is strong, resulting in a pin hit without losing revs and a very straightforward movement that makes the line easy to read. This product will be very useful on medium-dry conditions and will be an optimal product for center conditions.
