01Overview
The Storm Phaze II stands as a benchmark release in Storm's performance lineup, built to give bowlers a strong, predictable motion on medium to heavier oil conditions. At its core sits the Storm's proprietary asymmetric weight block, engineered to generate a sharp, controlled backend reaction without sacrificing the length needed to get through the front part of the lane. This core is paired with the premium NRG solid reactive coverstock, a formulation known for its aggressive traction on oil, allowing the ball to read the midlane earlier than many other releases in its class while still finishing strong into the pocket.
What sets the Phaze II apart is the balance Storm achieved between continuous motion and backend kick. Bowlers who favor a ball that can handle transition as oil breaks down throughout a game will appreciate how the Phaze II holds its line longer before making a decisive turn. The factory finish, typically box-polished to enhance length while retaining enough surface texture to grip the lane at the right moment, gives players versatility in how they can further customize the ball's reaction through additional sanding or polishing to match their specific house shot or sport pattern needs.
Aesthetically, the Phaze II carries Storm's signature bold color schemes, often blending deep blues, purples, and silvers in a swirling solid pattern that reflects the dynamic, energetic motion the ball is designed to produce on the lane. Beyond its looks, the ball's drilling layout versatility makes it a favorite among pro shop operators, as it accommodates a range of pin placements to suit different bowler styles, from stroker to high-rev player. For bowlers seeking a reliable, hard-hitting piece that can anchor their arsenal on medium-heavy conditions, the Storm Phaze II delivers consistent, repeatable performance frame after frame, making it a trusted choice among competitive league and tournament players alike.
