For sale is a used, excellent condition Storm Super Lock 15lb bowling ball, a popular series, with the original box. This ball features the RAD-X core and NeX pearl reactive coverstock, making it a strong pearl ball. It has three finger holes, with an IT thumb hole. I owned multiple balls, so this one has only been used for about 20 games. There are no major scratches that would affect the ball's trajectory, and the surface condition is good. However, please understand that this is a used item as shown in the photos before purchasing. Shipping is included in the price. Coverstock: NEX Pearl Reactive Weight Block: RAD-X Core RG: 2.48 (15lb) ΔRG: 0.054 (15lb) Mass Bias: 0.018 (15lb) The following is quoted from the High Sports HP: The latest addition to the Lock series is the "Super Lock," which features the popular "RAD-X core" and the pearl version of the "NeX cover." The cover provides moderate length and high friction, and the powerful core creates a strong backend and pin action. Popular + Popular, this combination that everyone has been waiting for! The NEX cover version finally arrives in the Lock series. This ball provides stable straightness from the release to the breakpoint, but the strong axis migration that occurs from the mid-lane, which is a feature of the RAD-X™ core, provides a powerful backend reaction after the breakpoint. This early axis migration creates a strong pin action that won't lose to the pins. The RAD-X™ core is the Radial Accelerating Disk™ core = as the name suggests, it means a core that accelerates rotation.
