Roto Grip TNT Review
While no longer in production, the Roto Grip TNT remains a solid option on the used market for bowlers who need reliable heavy oil performance. The combination of the eTrax Plus Solid coverstock and Torpex core delivers strong, predictable hook motion when lanes are flooded.
hey thanks for joining us everybody today I am giving you a look at the rotor grip TNT infused if you like what we do follow us on Facebook Instagram YouTube don't forget to subscribe and check us out on patreon First Impressions I have to say the TNT infused look like it could be something special all right let's get the usual out of the way the full surface of any
react to gloss finish ball th000 heavy on the spinner followed by step two compound and then a light 3,000 scuff by hand um no worries about being able to repeat that surface and it's less over under than the factory finish now onto business this thing just really impressed with its shape the TNT infused will obviously have length uh it's also angular but how it transitions seems the unique characteristic to my eyes it's a little hard to see on the video but in the
flesh there's a fairly easy length and then what appears to be a bit more push where you see the core transitioning it seems like a clear phase and that you can visualize and then a heavy turn over and roll dare I say reminds me a bit of the Marvel Pearl I mean I think the Marvel Pearl is a touch smoother but the phase transitions remind me of it it also reminds me I would say of the Highwire from a while back there's this sort of
touch forwardness through the pins that's like very late and the TNT infused I would say fits in the mid blade category uh but it is a step up from something like the IQ to a ruby almost like a mid late plus it's very interesting how this ball relates or doesn't to the original TNT The Benchmark type torpex core just seem to I flounder a bit in R Plus solid theoretically it wasn't super angular it wasn't super smooth but somehow I didn't
really find any consistent use for it I think the hybrid with some shine here really transforms the ball and somehow synergistic with the core Tyler's next and the TNT infused look just as good I don't want to repeat everything I said you can mostly watch the ball reaction with a higher rev rate still good length pretty angular look down Lane his eyes also like the look of the way the infused went through its phases at first glance it might look a
bit skid flip style on video but when you see it in person it'll be more clear don't get me wrong it's still pretty angular and Tyler can go high if he's not careful uh not fully surprising with a shiny ball and a house shot from deep but he understands the ball reaction and and it gives him comfort you can see that it's capable of covering boards and generating angle that doesn't seem to be a huge problem I would say because of the core shape it will give up a bit if you get too wide that's sort of what I mentioned
touch forward roll is enough to limit those huge angles Just a Touch however it's also what makes it great otherwise finally we have Brian testing the infused I have to say this is one of the best looks I've seen for Brian in a while the TNT infused as you expect at length like we say but the nice midlane and strong Arc that just seems so reliable and pocket controlling for Brian it really looked like the ideal
shape generally speaking Brian is excellent from an accuracy and pocket control standpoint regardless of the ball he uses the question tends to be whether a ball will drive well enough for let's say average versus above average carry the infused had that what I described as a kind of non- quitting turn that really carried very well for Brian uh rolls a little bit heavier because he's not covering a ton of boards additionally it was capable of generating angle for him when he moved
in and got around the ball at the end of the day the rotor grip TNT Infuse looks like it could really be a special type of ball reaction it it is mid lay but perhaps with a touch of surface even make its way up to a benchmark status like a mildly angular mid control ball bottom line is if you're looking for that Medium strong clean look the TNT infused is definitely worth a look storm definitely still has some magic up its sleeve when it comes to cover stock

Performance Analysis
Performance Analysis
Testing revealed that the Roto Grip TNT Infused delivers a notably refined ball motion compared to its predecessor. Independent reviewers observed the ball on house shot conditions and were impressed by its distinctive phase transition characteristics. The reactive solid coverstock paired with the symmetric core produces clear length through the front of the lane followed by a pronounced mid-lane push as the core transitions, culminating in a heavy, late-stage roll into the pocket. Reviewers noted this phasing behavior was easier to appreciate in person than on video, with the ball exhibiting moderate angularity without sacrificing control. The infused coverstock appears to synergize effectively with the core design in ways the original TNT formula did not, creating a more usable and versatile reaction shape.
On the test pattern, the TNT Infused demonstrated reliable mid-lane performance and strong pocket control across different rev rates and release styles. Multiple testers observed that the ball maintained good length while generating sufficient angle for board coverage when needed, though the core design does limit excessive angle if bowlers drift too far outside their intended line. Higher rev-rate bowlers appreciated the angularity and pin-action response, while those with smoother deliveries praised the ball’s non-quitting turn and carry characteristics through the pins. Surface adjustments from the factory 1000-grit finish (stepped to 3000 scuff) proved repeatable and produced less over-under behavior than the stock surface, giving bowlers room to fine-tune reaction to specific oil patterns.
Who Is This Ball For?
The TNT Infused is well-suited for bowlers seeking a clean, predictable mid-lane motion with enough angle to handle typical house shot conditions. It works particularly well for strokers and control-oriented players who value pocket consistency and carry over extreme board coverage—the ball’s design rewards accuracy without punishing small release variations. Bowlers transitioning from entry-level solid reactive equipment will find this a natural step up in both shape definition and performance reliability.
This ball is also an excellent choice for moderate to high rev-rate players who want defined mid-lane separation without committing to an aggressive pearl or hybrid. The TNT Infused fills the gap between over-skid equipment and heavy angular balls, making it a smart addition to an intermediate player’s arsenal or a dependable benchmark piece for those building a serious bag.
