Track Bowling decided we needed a stronger, more dynamic version of the 607A SE. With that thought in mind, we bring to you the all new 811A Special Edition featuring a brand new core, the “Legion 2 Turbo”. This unique core started out as a symmetric core shape but then was modified into an asymmetric core to get the exact RG, Differential, and Mass Bias numbers we were looking for. This perfectly tuned core is the “Heart and Soul” of the new 811A SE. With the Mass Bias being 0.011, this ball is set up to give the most angular backend reaction to the widest range of bowlers and styles. To go along with our new “Legion 2 Turbo” core we are also introducing an amazing new coverstock, the “SE8 GEN1” which includes “Crystalline Mica”, an all-new performance pearl additive. This additive is 15% more responsive off 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.
