Storm St17131blsi Flip Tote 1 Ball Bag Black/Royal Blue St17131blsi-

The Blue Hammer is an iconic throwback in performance ball technology. By combining a re-engineered Vibe core shape with our new Performance Urethane coverstock, we're introducing a ball that rolls like the old-school balls without actually being the old-school stuff. This new spin on older ball motion brings the control of yesterday's balls and the performance of today's stuff to the lane for Hammer! Performance Urethane coverstock. Finished with 800 abranet, 1000 abralon, 2000 abralon, 4000 abralon. Out of box Ra value is 3.0.Symmetric Drilling Instructions 10# RG 2.72 Diff 0.031 11# RG 2.62 Diff 0.031 12# RG 2.60 Diff 0.039 13# RG 2.53 Diff 0.055 14# RG 2.61 Diff 0.026 15# RG 2.57 Diff 0.032 16# RG 2.57 Diff 0.028
