Track Bowling

The Manufacturer’s Intent for the all new 811A SE is to be a stronger version of the 607A SE. We started with an all new core the “Legion 2 Turbo”. This core started out as a symmetric core shape and then was modified into an asymmetric core to get the specific RG, Differential and mass bias numbers we were looking for. This perfectly tuned core is the heart and soul of the all new 811A SE. With the Mass Bias being 0.011, it is set up to give the most angular backend reaction for the widest style of bowlers.

As for the all new “SE8 GEN1” coverstock, this is truly a remarkable breakthrough in coverstock design. We have developed an all new performance pearl additive “Crystalline Mica”. This additive is 15% more responsive of the dry than what was used in the 607A SE. You can clearly see in the SEM’s the difference between the SE6 coverstock and the new SE8. With the new core and coverstock, we were able to create the most balanced High Performance ball for the widest range of bowlers’ styles.
