Roto Grip has engineered the TNT upper-mid performance bowling ball to offer more torque and more power than previous low RG symmetrical balls. The core and cover combination on this ball create an explosive reaction, as the name suggests. This ball introduces the Torpex core which places the Torque Sphere just above the mid-point of the core. This design creates a low RG and a high differential which results in more motion and more continuation through the pins. The coverstock on this ball is the proven eTrax PLUS Solid Reactive. This coverstock provides more grip and response to friction while still offering ease through the beginning of the lane and ultimately more forgiveness on medium to medium/heavy oil.

Color: Amber/Fire/Blaze Orange
All colors do vary somewhat from the picture shown
Core: Torpex
Coverstock: eTrax PLUS Solid Reactive
Hook Potential: High
Finish: 2000-grit Abralon
RG: 2.47 (for 15# ball)
Differential: 0.052 (for 15# ball)
Recommended Lane Condition: Medium to Medium/Heavy Oil

Roto Grip TNT - HP3
Coverstock: eTrax+ Solid - 2000 grit Abralon
Core: Torpex
RG: 2.47   Differential: .052 (15 lbs)
Layout: 5 x 4 ¾  x 2 ½
PAP: 6" Right, 1 3/8" Up
Axis Tilt: 16°
Rotation: 51°
Rev Rate: 450-500
Speed: 17-18 mph
Location: Vista Lanes - Yorkville, NY
Pattern: Kegel Stone Street


TNT is dynamite with the Torpex core and eTrax PLUS solid coverstock. The torque sphere within the core creates a lower RG and higher differential which translates to more overall motion and less deflection through the pins. eTrax+ is cleaner than MicroTrax, but more aggressive than eTrax. The design intent was for the TNT to be a benchmark ball on medium to heavy patterns, much like the original Idol. The TNT gave me a good look to the pocket on the house pattern looking 15-16 at the arrows with my breakpoint around 7-8. As the lanes broke down I was able to move left, but not open my angles as the ball either overreacted off the friction or struggled to make the turn down lane. I expect the TNT to be an excellent ball on flatter, higher volume patterns because it is early, smooth, and predictable. It will slot below the Roto Grip Gem or 900 Global Realty and above the Roto Grip Idol Cosmos or Storm Phaze II. If you are looking for a ball that starts up early, but still provides great continuation, the TNT hits the mark! Stop by your local Storm VIP pro shop to check it out! Available on February 17th.

Roto Grip TNT review by Ethan Fiore

Length: 40

Type (THS, Sport Pattern etc): THS

Comments
The New Roto Grip TNT is your new benchmark ball. With the eTrax Solid Coverstock, it fits in that Idol and Phaze 2 range. Now when I compared the Phaze 2 to the TNT, the TNT was a lot earlier and smoother off the spot while the Phaze 2 was cleaner and more angular. Definitely see this ball fitting in the bag and recommend this ball to anyone who likes to play a little straighter or to players who throw it harder.

PAP: 5 1/8 R 7/8 Up

Ball Layout: Pin over Middle Finger 5 1/2 X 5 X 3 VLS

The new HP3 release from Roto Grip features a brand new core called the Torpex. The torpex design makes this ball extremely driller friendly and forgiving. They wrapped it in the Etrax Plus cover. The 2000 grit finish on this cover-stock gives you so much early motion, this ball is the most aggressive HP3 ball in the front of the lane to date.

I first tested the TNT on the high volume/ longer house pattern at my home center. I had managed to see a few reviews before I got ahold of mine. My worry with balls that have aggressive covers is that with my ball speed I will either:

A) Not be able to get the ball through the front
B) Not get the ball to retain energy when I do

Because of this I opted for a bit weaker layout on my TNT. The 5 1/2 inch pin to pap and 3 inch pin buffer will usually help cut flare and draw out the transition so that the ball doesn't lock up for me in the mid-lane. First couple of shots I was pretty surprised at how despite the ball definitely still seeing the mid-lane, it was actually much more forgiving that most of the balls I've been trying to throw game one.


Our lane beds are pretty beat up so to combat all of the early friction, there is a very high volume of oil used. The down-side to this is that the lanes begin to carry-down noticeably right out of practice. This gets frustrating because the fronts can get chewed up pretty fast and the backends stay tight so the balls that are stronger in the front get too early and the down-lane oil makes it difficult for them to recover. It was actually a problem I had trouble combating until I threw the TNT. This ball's ability to always see the mid-lane really takes the backend out of play. It doesn't stop either, so it's very forgiving on errant shots. Our ratio is pretty high and this ball really lets you take advantage of it like no other ball will.

Now that I've had a chance to throw it and stay in it so long because of the down-lane forgiveness I'm pretty sure I want to try one with a stronger layout too for when I need the ball to slow down a bit more down-lane. So much for my initial worries. I would recommend this ball for those speed dominant bowlers who need the early motion and for any style bowler who ever runs into an issue with getting their ball to react consistently down-lane. The layouts you can choose to make this ball useful don't really shut anyone out of using he TNT.

Bowlers Info: RH tweener, PAP 4-5/8 x 3/4 up, 380 RPM, 13* of Axis tilt, 60* of Axis Rotation

Ball Layout: 45 x 4-1/4 x 75
VLS: 4.25 x 4 x 5.5

Finish: OOB

The TNT is the newest strong symmetric piece by Roto Grip.  After seeing the numbers on this ball, I was need of a strong, controlled piece in my tournament arsenal and that’s exactly what I got.  I drilled mine 4-1/4” pin under my ring which gets this piece rolling early and control the backend for fresh sport shots, shorter sport patterns, or the first couple of games of league.  This ball is big and early which can be a great control piece with big hitting power!  I really don’t see this as a “stand left, throw right” piece as the cover is very strong.  Polish can be added to increase skid and retain more energy on the backend.  This will be a benchmark piece for sure where this ball can tell you what the lanes are giving you.  If you’re looking for an early rolling piece, this one will not disappoint with its hitting power!!

Roto Grip TNT
Coverstock: eTrax PLUS Solid
Core: Torpex
Factory Finish: 2000-grit Abralon
Layout: 3.5 x 6 x 3

The TNT is Roto Grip’s new HP3 ball with the Torpex Core and ETrax Plus Solid coverstock. The HP3 line is the birthplace of the Idol so the TNT has a lot to live up to. After watching some videos of the TNT before I drilled it, I saw a really strong ball that definitely appeared early and on the rounder side of reactions. I did not use a standard layout for my TNT. I put the pin in my ring finger for a 3.5 x 6 x 3 layout to try to take advantage of the characteristics of the ball. My TNT reads the lane pretty early and definitely has more of a slow, arching motion that will be great when control and stability are required. I can’t open my angles up much with the TNT in its out of box surface, but if i keep angles a bit more closed and square, it hits like a tank. Compared to balls in the Roto Grip line like the Idol Cosmos and Exotic Gem, the TNT is much more slow and controlled with the Cosmos and Exotic being more responsive. In summary, the TNT is a unique ball. It isn’t going to wow you with backend, but it does provide a great purpose in my bag. It blends wet/dry house walls well and it controls flatter patterns because of how slow it is on the lane.

The TNT is designed to be a benchmark type reaction. I think mine is a bit strong to be a benchmark ball with my chosen layout, but I feel like it could be for bowlers with lower rev rates and/or higher ball speeds.

Roto Grip TNT – WWRD 2/17/23
Cover: eTrax Plus Solid Reactive
Core:  Torpex Core
RG: 2.47
RG . Diff. 0.052
Finish: 2000 Grit Abralon

Roto Grip’s new TNT is a Symmetrical Solid piece that is good for Medium Oil conditions.  PAP is 5 5/16 R 1 3/16 Up. Rev Rate: 400.  Speed: 16.5.  Drilled this piece with the Pin up between the fingers and CG kicked out 1” from the palm.   Out of Box ball motion started early in the mid’s with a smooth motion on the backend.  I changed the Surface with 2000 & 3000 Abralon similar motion through the fronts with more backend motion.  I compared this piece with 3 pieces on a Fresh House Shot pattern.  The Hustle PBR 4-4 Right was a few feet further down lane with more backend motion.  Hustle Camo was 3-3 further right but cleaner through the fronts and sharper backend.  And Idol Helios was 2-2 Right with a smoother and a little stronger on the backend.  This piece is good for High rev bowlers.

Likes:

Fresh off the press 258 - 279 - 233 for 780.

I did not expect to be able to throw this ball with the out of box surface being at 2000 grit, but not only did it strike, but it struck all night.  I fully expected that I'd throw a few shots then put it away before I took it to 3000, where I thought I'd need it, but this ball rolled great right off the press.  Strong in the mid lane but still continuous on the back end.  Normally, for me, balls with that much surface will make its move and then just roll out. The TNT, however, it just kept digging and hits like a truck.  I really like the way it shapes up in the mid-lane, if your looking for mid-lane reaction and continuous drive, this is the ball for you. This one might stay in the bag for a while. Contemplating drilling a 2nd one to polish, might be just as good.

Dislikes: None so far.

The all new TNT fills a major hole in the SPI line that I have personally been looking for lately. SPI has been missing a low RG symmetrical solid with a strong cover like the eTrax Plus Solid coverstock featured on the TNT. This ball by the numbers (RG/Diff) is extremely close to the Phase II, however, the new eTrax Plus Solid coverstock gives me more grip and responsiveness to the friction. This ball will be extremely good when I need to blend out wet/dry lane conditions. Historically, symmetrical balls roll better for me than asymmetric cores so I am excited for this ball to go into my tournament arsenal so I can have a ball with a strong symmetric core/cover combination that I can help me hook it with the best of them on long/high volume oil patterns. This ball will be a must have for tournament bowlers looking for a strong controllable motion on longer fresh oil patterns.

TNT
Coverstock: etrax PLUS solid with 2000 grit finish
Core: Torpex (symmetric)

Review:
If you are looking for a new benchmark ball, look no further than the TNT. This ball reminds me a lot of the original Idol. I found that the TNT did read a little earlier than the original Idol, but overall I felt that ball was cleaner than the Idol. This ball really likes to move when it hits the lanes. This provides the bowler and opportunity to use this ball on many different conditions, from the typical house shot to the higher volume patterns. Even with how strong this ball was I found that it was very controllable and predictable down lane. Just like the Idol I can see this ball in my bag for a long time, make sure you pick yours up as soon as they are available.

Core • Torpex Symmetric Core
Coverstock • eTrax PLUS Solid • Finish 2000-grit Abralon
Weight • 15 lbs. RG • 2.47 Differential • .052
Layout • 4 x 41/2 x 21/4
Tester PAP • 5” R, 5/8” D Tester Axis Tilt • 11° Testers Rev Rate • 325
Test Pattern • 42’ THS (Typical House Shot) • Modified, Kegel Stone Street


Roto Grip has delivered an explosive new release with the TNT. And from my first roll with the TNT, it was obvious that Roto Grip heard the needs of down and in players like me. And they responded with a powerful new weapon to keep the THS (typical house shot) bowler in the fight! So, let’s take a closer look at what makes the TNT potent ammunition for your game.

The Torpex symmetrical core seriously caught me off-guard! I liked how the Torpex core fights to stand up but does so in such a smooth and continuous roll that I didn’t expect to see the power it unleashes when it strikes the pins! Because of my down and in and low rev style, symmetrical cores tend to roll out and run out of gas as they get to the pocket. That is not the case with the TNT! The Torpex core hits seriously hard and has a continuation that rivals some of my bigger asymmetrical cores balls. And lastly, I thoroughly enjoyed the predictable motion the Torpex delivered for me, shot after shot.

Now, let’s talk about the ETRAX Plus Solid coverstock. I found the ETRAX Plus Solid to be a thick oil-absorbing cover without being overly aggressive. And the 2000-grit Abralon surface makes it ideal for THS conditions. Being a straighter player, I liked how the ETRAX Plus found strong traction early in its roll but still allowed the TNT to detonate its power off the pattern. And as the conditions transitioned and headed into game three. I appreciated the ETRAX Plus Solid’s ability to blend the wet/dry and spotty conditions to give me the same smooth look all night.

The One caveat I have for the ETRAX Plus Solid is because of its porous and absorbent nature. I would highly suggest keeping it clean. Wipe your TNT between every shot, and use a good cleaner at the end of your league play. Further, have the oil extracted every thirty or so games to keep it fresh and crisp. The ETRAX Plus Solid is a robust solid cover that will last you a very long time with the proper maintenance.

In conclusion, Roto Grip has produced a winner with the TNT. I highly recommend the TNT for straighter, high-speed, low-rev players like me. And if you are a weekly league bowler, the TNT will deliver top-tier results at a mid-level price, making it a great “bang” for the buck! So, stop into your local Storm VIP Pro Shop and have your TNT drilled up for tonight’s league! The results will be dynamite!

Roto Grip TNT by Casey Murphy
« Reply #11 on: March 11, 2023, 11:16:07 AM »
Orientation:  Right Handed
Rev Rate:  400 RPM
Speed:  16-17 MPH
PAP:  4 ½ over and ½ up

Location:  Enterprise Park Lanes, Springfield MO
Pattern:  High Volume THS
VLS Layout: 
Layout 1:  5 x 4 x 2 ½  (pin above bridge)
Layout 2:  4 ½ x 4 x 4 1/8 (pin below bridge)

The TNT is a new solid sym from Roto Grip.  It features the Etrax Plus Solid, which is a Solid version of the X2 cover.  The Core is new too and features a slightly lower RG and same Diff as the Idol.  The result is a ball that is strong but still revs up and tips a lot more than you think.  I took mine up to 4k on the spinner and let it lane shine a little.  It’s still very strong but it gets though the fronts and tips plenty.  I have a pin up one that I throw a lot on the fresh and it rolls great and I have a pin down I like almost as much (I had a 21 bagger to start the night with the pin down one).  I have the TNT as the strongest overall symmetrical that we make.

Review:
I am extremely happy with the new Roto Grip TNT. I have not shot a low game yet with this ball. The TNT fits right between the Hustle USA and the original Gem in my Roto line up. The TNT is also above the Hyped Solid in total hook. The TNT rolls up early but just keeps coming with no quit. The TNT is not an angular ball but has a powerful controlled motion throughout the whole lane. This ball hits great and carry is excellent for a smooth ball. I bowled on a difficult lane condition for the video with the TNT and it overcame the pattern. The lanes had a ton of carry down and back end move was hardly there. This was for all bowlers and balls that went down the lane that morning.  I was impressed by how the TNT would set up high flush without over reacting and also carried light hits with power. On our oilier house shot when I need a ball with more bite but control the TNT has been excellent. I am going to drill up my second one and polish it. I feel I will be equally pleased with that set up. We have drilled a good amount of these so far for my customers and we have seen great ball motions from a variety of styles. This ball looks great on the shelf and even better going down the lane.

Summary:
The TNT is becoming one of my favorite balls to roll right now.
The TNT has a very strong continuous motion.
The TNT works great on house shot and should be great on sport patterns as well.

Roto Grip TNT
Coverstock: eTrax Plus Solid Reactive
Box Finish: 2000-grit Abralon
Core: Torpex Core
RG: 2.47, Diff: 0.052 (15 lbs)
VLS Layout: 4 1/2 x 5 x 2
Dual Angle Layout: 60 x 4 1/2 x 30
PAP: 5 3/16” right x 5/8” up
Rev rate: 400 rpm
Average speed: 16.5 mph
Location: Prairie Lanes, Sun Prairie, WI
Pattern: Medium volume THS

The TNT is the newest ball in the Roto Grip HP3 line.  It features a new core design that creates the lowest RG symmetrical core ever, and a high differential which translates to an early and consistent ball motion with less deflection going through the pins.  The cover features the solid version of eTrax Plus, which was first used in a pearlized form on the RST-X2, and provides increased traction for a forgiving reaction on the lane.

With the Roto Grip TNT, I’ve seen early and continuous ball motion which has been very much needed in my arsenal.  It’s a step down from the Roto Grip Gem but is above balls like the Idol Cosmos.  The TNT gives me a very strong and stable reaction which can be great for blending out over/under league conditions, but I think this will be even better on shorter to medium length sport/challenge conditions.  Specifically, I’m thinking this could be a really good ball to start with for the USBC Open team event, then once the lanes settle in moving into something that’s still strong but a bit cleaner. 

I’ve left the surface on my TNT at box finish, and plan on keeping it near the 2000-grit Abralon factory finish so that I have that stable and forgiving benchmark-type ball reaction in my bag.  This will be a must have for tournament bowlers, but I could certainly see others bringing it up to either a 4000-grit or polished finish to help it retain more energy and shape for the backend.  Either way, the TNT will undoubtedly be blowing up racks!

Ball Specs:
Roto Grip TNT
Cover: 2000-grit abralon eTraxâ„¢ Solid Reactive
Weight Block: Torpexâ„¢ Core (Symmetrical)
Color: Amber/Fire/Blaze Orange

Review:
This is a great release from Roto Grip. The technical data has benchmark ball written all over it. We drilled this ball with our normal layout: tweener, 350-375 revs, 16.5mph, layout of choice is 4x4x2 (pin is above bridge). This ball compares closely to the Phaze 2, so those of you who love Roto and are looking for that GOAT sort of ball, this fits in perfectly. This ball does like oil, and speed, or a good combination of both to be honest. Slower ball speeds may want to take the cover up to 3000 or 4k to see a little more length. This ball is incredibly continuous and it really does speak to its name when it hits the pins because they do seem to fly different. We see this ball easily being that next ‘house shot killer’ and we expect this bowling ball in a lot of customers hands. Visit your local Pro Shop Operator and ask about the TNT today!
