Thanks to the relentlessness of our research and development team, we found yet another way to formulate quite possibly the most explosive benchmark balls in recent history. Engineered to create more overall torque and pure projectile power than all the low RG symmetrical ball before it, the TNT is here to blow up racks and take names. From the Torque Sphere Technology inside the Torpex Core to the introduction of the eTrax™ PLUS solid coverstock, it’s a high probability this ball will have your opponent’s taking cover and calling the bomb squad for help.

By placing the TORQUE SPHERE just above the inner equator of the TORPEX Core, we found that not only did it create the lowest RG symmetrical Roto Grip part ever, but it also created a higher differential which translates to more overall motion and less deflection through the pins.

First introduced in the pearlized form, we felt there was no better time than now to unleash the solid version on this brand-new core shape. Providing more overall grip and responsiveness to friction than our forever famous eTrax solid coverstock, this cover is still a step down from our super aggressive MicroTrax solid coverstock material. Bottom line, cleaner through the front of the lane than MicroTrax, but overall, more aggressive than eTrax.

Engineered for Medium to Medium/Heavy Oil Conditions.
