Roto Grip TNT Infused Review
While no longer in production, the TNT Infused remains a solid heavy oil option for bowlers seeking strong hook potential and excellent pin action. The combination of the Torpex core and eTrax Plus Hybrid coverstock makes it ideal for challenging lane conditions, though availability is now limited to the used market where it can often be found at attractive prices.
welcome back to the channel we have new balls we got Magic Gem and TNT infused so Magic Gem very strong ball hybrid version of the gem which is the solid version exotic gem is the Pearl and I believe this one is going to be much much closer to the original Gem and we're going to throw some shots and I'm going to explain to you why so gems strongest balls we have in this spot it's probably not going to be very good but I'm going to throw here anyways or or or or or I don't know we're bowling on I threw some shots to
the right threw some shots to the left one thing is certain there is a lot of hook in the front of the lane and that's a pretty common theme at Gold Coast which is where we were bowling here in Las Vegas strong bowling balls with strong covers with a lot of surface don't mix well with that we're going to do what we can to navigate our way and try to throw some strikes I'm not going to guarantee anything except that my ball reaction may not be the best I'm taking a pretty good chunk to the left my main concern here is when I manipulate my hand it's going to see the front of of the lane these really strong bowling balls are really responsive to
friction when they see it they respond to the Lane fast if that doesn't make any sense we have a lot of resources where we can try to explain that we got the course in the description below we have twitch I can try to explain it in person not in person but live but we're taking a big chunk to the left here maybe a little bit of Loft too to get over that front part of the lane curve hey you see how it's just Str struggling so hard to get down the lane and it doesn't want to make the corner so there are a lot of things we can do
here we can try to up the ball speed to get through the front but if we do that the ball may not retain enough energy because it's still fighting that front part of the lane add axis rotation which is probably what I'm going to do here or move left which is also what I'm going to do we're getting the full full range of potatoes with this ball so far not too bad potatoes not too bad the full potatoes full sack the hooked potato you got the standard play where you're normally going to play potato you got the I don't feel great about the
straight ball potato right now cuz they hook so early and I'm going to feel like I have to fluff it and throw it hard but we can move around but I just want this to be a learning experience for everybody the same ball is not always going to work you got to throw the right ball at the right time and Jesse even said we should probably oil to make the ball look better I'm going to tell you guys the truth right now with how much friction there is out in the lane this Ball's not going to look great that one might be good oh that's for Packy and one for the boys and two and two and two so I look at
that shot yeah cool we got the messenger we kicked out the 710 but I see that I go man I might leave the 710 so I'm thinking about different things so I have a gem an original gem here with me how does that compare to the Magic Gem think is a little stronger my Magic Gem has 5 1/2 by 5 by 2 and 1/2 layout this one is slightly stronger so I expect it to be a little bit earlier might come off a spot a little bit harder as well well this one is 5X 5x two so a pretty strong buffer it's going to get it to transition quicker AKA read earlier taking those things into account maybe
we just play the same spot I thought it was pretty close honestly I thought it read the front even harder I want to call it a more defined shape you know it wants to hook early and it wants to get going forward pretty quick the Magic Gem was kind of a little more on the uh I kind of want to get through it a little more I kind of want to give it a little more down Lane and that's probably because it's a hybrid but even so if I had an exotic gem with me it would probably look a lot better cuz it would get through the front easier but Magic Gem definitely closer to original gem honestly you
could probably replace your gem with the Magic Gem it's kind of how I'm seeing it right now I don't know if you guys can see it my ball hooking really early and it's just locking up it's going to have a really hard time getting to the right and then making that big cool down Lane motion that most people like to see I like my banana shape I like my ball to read the front of the lane but this is just a little too much so I know a lot of people like to see the around 10 shot and again this isn't a house shot so if
I get to going to the right too fast and I fluff it too much it's probably not going to hook I'm going to do what I can here it's just it's just so early that it has almost no chance to stay online I'll try to get a little steeper for you guys and get it going to the right but when I'm having to do this many different things usually it's a ball change so we'll try one more and then we'll check out the brand new TNT infused which I guarantee will look a lot
better on your typical house shot I think that hooks so that's kind of what told me this isn't a house shot I moved to the right I tried to play to the right get it there quick usually that house shot's bringing everything back to the pocket this isn't doing that TNT infused I have thrown both of these already before threw them yesterday I actually threw them in League actually my best league night ever not ever but best league night this season so far okay we're going to check out this infus in the same spot and then we'll move around the lane and see if this looks
better so it's still pretty responsive really strong core fairly strong cover it's just a hybrid version of the TNT two part pearl one part solid so it's like a different bowling ball not even close to the same and I know this video is going up later than most of our new release videos but I've got a chance to watch this ball go down the lane a little bit especially in other Ball Reviews TV bowling supplies in particular my brothers I think he explains things very well for these two balls having the same core and just different covers they could not be more different TNT original really smooth
really strong how many parts Pearl it has makes it way more responsive I think it's going to be a little more user friendly in league and uh it's going to allow the people like to hook the ball to hook it a little more so that was about three with my feet further left that looked pretty good and just how much frictions in the front of the lane is not allowing the ball to get to the right my fear here is if I keep going I'm going to find that little slot where it just keeps going so maybe we don't fear that maybe we just embrace it stay steep get slow get around it big
angles it definitely looks way better than the gem right now but seeing that I felt like my ball tried to hook like three times before it actually made its move I'm still thinking I need a cleaner ball when the lanes get super chopped up these Mega strong bowling balls probably aren't the best option when do I throw these bowling balls though when you do feel like your balls are having a hard time hooking when you need to blend out maybe the flatness of the pattern you feel like there's hang right hook left these big balls will read the pattern a little earlier blend that out for you so it should want to try to hook a little more when it gets to the right and blend it out when it sees friction cuz it's
reading the lane that much earlier but when you see a lot of hook in the front these are not the go-to balls I don't know if you guys have noticed but I'm manipulating every single shot a good amount so that's a good indicator that you may not be in the right ball although this one does look pretty good right now so I'm not not complaining so let's compare TNT I'm going to go back to that first spot where I wasn't rotating the piss out of it unlike Mikey's video he likes his TNT is a little shinier because of how strong this bowling ball is I keep mine
with some more surface just to get it reading the front of the Lan a little more and my ball doesn't read the front nearly as hard as my brother's so that is probably the difference hooked way earlier I did move back to the right but that Ball's got the most surface out of the four I have today so naturally it's going to read the front of the lane pretty early and in terms of cover stock strength Just a Touch lower than the gems so keeping that in mind this is essentially one of the strongest symmetric balls we make so whether you want to go or asymmetric if
you want a really strong option TNT gem those are the plays now this is in the same spot as the infused I'm going to rotate it just the same and we'll see what happens here that's expected and I know a lot of newer viewers are going to look at that and go if that Ball's stronger Why didn't it hook more the way higher level Bowlers see strength is how early a bowling ball hooks this ball is hooking way too early so it's not going to have
enough energy to hook what do we do now if we want to try to use the same ball throw it slower we find more oil we go further left and uh hope it's a good guess maybe even more axis rotation to help it get through the front that was pretty good but again yeah a lot of rotation there's a range that everyone has when I roll it's like 30° when I'm getting around at 65 70° when you get further away from what you're used to doing or your a game it gets a lot harder to repeat so if I
could just throw infused instead of having to rotate the hell out of it and give it my close to 100% axis rotation it's going to be really hard to repeat that 100% so if I'm just throwing the TNT Infuse at maybe 75% of my range it's going to be a lot easier to repeat at 75% than the 100 so we'll be in the same spot here definitely not going to have to rotate it as much and it'll be a lot easier for the ball to make the corner
you want to think about your ranges physically you know if we're talking about speed if we're talking about axis rotation even rate how much you can change those things and then think about your comfort level in which you're doing them now sometimes you're just your back's up against the wall you have to do what you have to do and that's what happens a lot on tour for us you know we're here at home bowling lead your box is probably pretty small you don't really have to do a whole lot different to achieve success but out on tour the possibilities are endless so that's why versatility is really important I know this is a ball video but we always like to give little tidbits of information to
help you get better versatility is going to be huge in allowing you to have more than just let's say I have these four bowling balls have more than four bowling balls if there's two different things I can do now I have eight if there's three different things I can do now I have more and the more you can do the more that just compounds how many options you have in the GRE scheme of things this is Magic Gem and TNT infused I hope you guys learned enough to make an educated decision in the Pro Shop and if you didn't make sure you guys check out our link down below we have a course that teaches you everything you need to know about bowling and if you guys are
interested in seeing how these balls fit into a six ball Arsenal stay tuned we have a video on that coming very soon
Performance Analysis
Performance Analysis
Testing revealed that the Roto Grip TNT Infused performed significantly better than stronger symmetric alternatives when faced with heavy friction in the front of the lane. On the test pattern at Gold Coast in Las Vegas—characterized by substantial early-lane hook—independent reviewers observed that the TNT Infused’s hybrid coverstock provided a more usable motion compared to pure solid-cover counterparts. The ball demonstrated a defined hook shape with earlier midlane read, yet it retained enough energy to reach the pocket without requiring extreme hand manipulation. Surface adjustment proved to be a key factor; maintaining moderate surface on the coverstock helped the ball read the front-lane friction appropriately without over-responding to the lane condition.
When compared directly to the original TNT (pearl) and the Magic Gem (hybrid), the TNT Infused occupied a practical middle ground. Testing showed it hooked earlier than the pearl version but with greater control and repeatability than the stronger pure solids. Reviewers noted that the symmetric core with hybrid coverstock combination allowed bowlers to operate comfortably within their natural delivery range—typically around 75% of their physical capability—rather than requiring extreme axis rotation or speed adjustments to find the pocket. This translated to more consistent shot-to-shot performance, particularly on house conditions where excessive early-lane friction can punish overly aggressive coverstock blends.
One notable observation was that the TNT Infused’s strength made it less ideal for pristine, freshly-oiled patterns but genuinely useful when lanes developed character and oil distribution became uneven. The ball’s responsiveness to friction allowed it to blend out hang points and inconsistent reads that plague many bowling balls in high-friction scenarios. However, on heavily chopped-up conditions, testing indicated that cleaner ball motion might prove more versatile for the majority of league bowlers.
Who Is This Ball For?
The TNT Infused is best suited for league and recreational bowlers operating within moderate oil patterns who want a no-nonsense heavy-oil tool without the complexity of extreme adjustments. Bowlers who struggle with hand control or those who prefer to stay within their natural delivery style will find this ball more forgiving than pure solids of equivalent strength. It serves as an excellent complement to a small two- or three-ball arsenal, functioning as that “medium-strong” option between a benchmark benchmark ball and a pure heavy-oil specialist.
This ball is also ideal for bowlers who experience inconsistent lane conditions throughout their league season—those environments where oil breaks down unpredictably and creating a defined shape becomes valuable. Players who occasionally need to blend out flat spots in their shot without committing to the extreme friction-reading behavior of the strongest solids should add the TNT Infused to their consideration list. However, bowlers who bowl exclusively on fresh, heavily-oiled patterns or who prefer smooth, downlane-oriented ball motion should evaluate the pearl TNT before committing to this hybrid version.
The Pros
- • Strong hook potential with eTrax Plus Hybrid coverstock
- • Excellent pin action and carry
- • Effective on heavy oil conditions
The Cons
- • Limited versatility outside heavy oil patterns
- • Discontinued status makes availability scarce
