"Likes" from those who do not intend to purchase are not needed. ^_^ I am having trouble with many people who do not read the seller's name, product description, or profile. This is a Roto Grip TNT. Only test thrown. It was hidden in the back of the ball storage. The Torpex core installed in the TNT has a good backend, but its rolling from the midlane is excellent. Roto's characteristic good control. The specs are also good, please refer to the box photo. I will not answer questions about the pitch or grip size. Please consider it assuming plugging. Of course, there are no plugs. When listing, I checked it again, but I didn't see any strange scratches. I polished the surface to check for scratches. The reason is that you can see the polishing powder attached to the scratches. I will not write that it is an "ultra-beautiful item" when it is a second-hand user who has plugged it once (sometimes more than twice) and the condition is also reasonable, or that it has been thrown until the logo is thinned out or peeled off, or that it has been thrown less than 30 games. You can rest assured because the origin is clear. I have described the condition without exaggeration. ● Coverstock: eTrax PLUS Solid Reactive ● Core: Torpex Core ● Surface Finish: 2000 grit Abralon → Polish ● RG: 2.470 (15lbs) ● ΔRG: 0.052 (15lbs) ● Mass Bias Difference: N/A ● Hardness: 73-75 degrees ● Flare Potential: High ● Suitable Conditions: Medium, Medium Heavy The center of the ball is equipped with a new core "Torpex Core" with a specific gravity. eTrax PLUS Solid Reactive, which is highly reactive, is used for the coverstock. It goes straight with moderate friction without rolling too much, and produces a strong roll at the backend, with a stable curve, making it easy for various bowlers to throw. Its intense pin action is the crystallization of Roto Grip's cutting-edge development technology.
