The Strata is Track’s first top-end release this year. The Proof performed like the highest priced balls but was sold at a great value. The designers had the challenging task of exceeding the Proof’s performance with this release, and we’re all very excited with the results. The Track Strata bowling ball provides the ideal blend of strong mid lane with continuous backend. To get the desired performance, the Track design team started with the new Strata core, and the strongest Q.R. cover to date, QR-11 Solid.

The order was really great! I ordered a 14, but got a 15- and the replacement was sent right away. I got to roll my Strata and believe that its a great compliment to my Track Arsenal. We'll see if I can roll another 300 and simultaneous 800 series!
