Roto Grip TNT
« on: February 16, 2023, 08:49:49 PM »
The HP3 line has been a HUGE success from Roto Grip since the beginning. The TNT brings a new core with an successful cover. The Torpex core has an RG of 2.47 and a differential of 0.052 and is wrapped around the eTrax+ Solid cover. I drilled mine 5 x 5 x 3 and I’ve had a lot of success with balls from this line with that drilling and similar level line balls. Balls like the Idol, Zen Master and Idol Pro just to name a few. After throwing my TNT for awhile I know this is going to be a MUST have ball. It’s a touch cleaner than the Zen Master and doesn’t rev up as much. I’ve bowled on multiple patterns and I can’t believe how versatile this ball is. I am able to keep my angles in front of me and when the lanes started to break down and transition this ball allowed me to keep moving in and opening up my angles. Don’t miss out on getting a TNT today !

Roto Grip TNT
Layout: 4.5 x 4 x 2 Storm Pin Buffer Layout
Rev Rate: 325 rpm, 7 degree of axis tilt, 40 degree of axis rotation
Testing information: 41 foot THS (medium to light volume)
Bowling Center: Fulton Bowling Center
Kegel Machine – Brunswick Anvilane

The Roto Grip TNT combines the Torpex Core and eTrax Solid cover.  The TNT gives off Idol and Haywire vibes but is a touch stronger.  This is expected with the improved technology that Schlem puts out of the
Roto Grip R&D Lab.  We liked the controlled motion of the TNT.  I see it fitting between your Exotic Gem and Idol series bowling balls.  I will use it early in tournament blocks to control the pocket until the lanes open up.
