"Likes" from those with no intention of purchasing are not needed. This is the Storm Summit. The ball is a very good ball. The color is too plain for me, though^_^ However, the ball itself is very popular, and I remember it quickly went out of stock at the manufacturer. It is equipped with a Centripetal core, which is installed in the Marvel, with AI. It adjusts the rolling start. Although it's a symmetrical core, I feel it has a unique, asymmetrical-like movement. Due to circumstances, it was stored after being used for about 10 games. It has a 3-hole drill for right-handed bowlers. The grip is almost new, so I removed it. For the listing, I re-surfaced it → applied Reacta Gloss. There might be some polishing dust on it. I checked it again, but I don't think there are any strange scratches. The color of the logo seems to be faded, but it might be polishing dust. The logo engraving remains deep. I have described the condition without exaggeration. The specs are also good. Please refer to the photos. Before drilling 15-2 TW 3.2 The box is missing, so it will be shipped in a different box. Coverstock: TX-23™ Hybrid Reactive Core: Centripetal™ HD-A.I. RG: 2.460 (15LBS) Differential: 0.056 (15LBS) Flare: High Hardness: 73～75 The new "Summit" series, which adopts the newly developed Centripetal™ HD-A.I. core, has arrived. By matching the Centripetal HD core, which has a different specific gravity based on the Centripetal™ core, with a new AI outer core, it demonstrates the best pin action with a more powerful roll. It also inherits the advantages of the conventional core, and the high straightness and the ability to adapt to lane changes are also attractive features of this ball. It shows a curve that is between a sharp break and an arc-shaped curve. Normally, the ball's numerical values change depending on the weight, but the "Summit" has been improved to be closer to the same values. In addition, the coverstock "TX-23™ Hybrid Reactive" allows for use in a wide range of conditions. It also has high rolling durability and causes the best pin action.
