This is a new Storm IQ Tour Purple ball from High Sports. Please refer to the outer box in the photos for the specifications. The following is quoted from High Sports: This IQ series offers excellent lane-front performance, unwavering roll in the mid-lane, and a moderate backend reaction. It can maintain straightness even with less oil, making it especially suitable for the latter half of tournaments and bowlers with slower ball speeds. This time, we've adopted R2S Pro Pearl Reactive, which makes it easy to achieve a straight trajectory. It continues to roll with moderate friction from the mid-lane to the backend. It also has a good reaction from the breakpoint, producing a powerful arc-shaped curve. There is no wobble after hitting the pins, suppressing power loss and creating intense pin action. Because there is no wasted movement, this ball is very easy to throw even if the oil on the front of the lane is thin.
