Report Card: Roto Grip TNT | Luke Rosdahl

This is our review for the new 900 Global Eternity Pi bowling ball!

When it comes to bowling equipment, no one knows the game quite like BowlersMart. As a trusted and reputable retailer with a deep understanding of the sport, we have had the honor and privilege of testing some of the best products on the market. That’s why we are excited to share our insights and review of the Roto Grip TNT bowling ball.
 
Let’s get right to it – this ball is a game-changer! Its innovative technology delivers a powerful and explosive hit that sets it apart from other balls on the market. This ball has a dynamic weight block and an symmetrical core that provides precision and predictability, allowing you to make accurate shots and level up your game.
 
What also makes the Roto Grip TNT unique is its versatility. It’s a ball that can handle various lane conditions, from light to heavy oil, thanks to its reactive coverstock. It’s truly a valuable addition to anyone’s arsenal, whether you’re a beginner or a seasoned pro. If you’re looking to take your game to new heights, then look no further than the Roto Grip TNT bowling ball.

Roto Grip TNT Bowling Ball

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

TORPEXâ„¢ CORE
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.

ETRAXâ„¢ PLUS SOLID COVERSTOCK
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.
