Three different color variations and weights of bowling balls, each with a different coverstock and finish to enhance performance. I am selling these due to moving and decluttering. Please note that due to my move, the auction may end early and shipping may be delayed. Isn't the first generation Physix quite rare? This is first come, first served. - Brand: PhysiX Grandeur - Color: 3-tone Blue - Weight: 15LB 3OZ - Coverstock: R2S Solid Reactive - Ball Finish: 4000-grit Abralon - Top: 2.56 - Pin: 2.5-3 - Brand: RST X-2 Pro - Color: Forest/Fire Red/Black - Weight: 15LB 4OZ - Coverstock: Hyper Response™ Pearl - Ball Finish: 1500-grit polished - Top: 3.12 - Pin: 3-3.5 - Brand: PhysiX - Color: Red/Blue/Purple - Weight: 15LB 3OZ - Coverstock: NRG Hybrid Reactive - Ball Finish: 3000-grit Abralon - Top: 3.05 - Pin: 2.5-3 Thank you for looking.
