- Quantum Evo Pearl

First Impressions
The Brunswick Quantum Evo Pearl comes in an attractive Royal/Ruby/Black color scheme and represents a technological evolution of the classic Quantum series. At its heart works the asymmetric QCS-24 core with a 2.511 RG (15 lbs), a 0.053 differential and a 0.024 intermediate differential. The cover is the Evolution Reactive Pearl coverstock with a factory surface of 500/1000/1500 SiaAir plus Crown Factory Compound polish. The characteristic mushroom core design has been modified with integrated flow channels that make the DynamiCore2 technology possible and should provide better durability and hitting power.
Comparison
Compared to the Brunswick Quantum Bias Pearl, the Evo Pearl offers a stronger overall reaction with a more pronounced, sharper backend movement. The higher intermediate core value was strategically paired with the polished surface to promote an increased friction response. While the Quantum Evo Solid uses the QCS-12 core with a lower RG and differential, the Pearl works with the QCS-24 system for different reaction characteristics. Compared to the Storm Phaze II Pearl, which positions itself between the Phaze II Solid and the IQ Tour series, the Quantum Evo Pearl shows a more direct approach to backend reaction. With a reaction shape strength of 82, it slots into the upper performance segment.
On the Lanes
The ball is ideally suited for medium to heavy oil conditions and should both provide increased hook potential in more oil and retain the typical pearl characteristics on breaking-down or transitioning lanes. As a strong asymmetric ball, it offers length with a powerful move when it contacts friction. Bowlers report having to start about 5 boards further left than usual, since the ball reads earlier than typical pearls, yet stores its energy and hits very hard. The easy length allows energy to be conserved for a big move at the end of the pattern, while the ball is not overly oil-sensitive and makes it possible to follow the breaking-down pattern inside. Both closed and open angles are possible, with the ball retaining its energy on the backend.
