Roto Grip created the TNT Infused bowling ball with a focus on achieving both length and forgiveness. This ball is a benchmark in the Roto Grip line, featuring the same Torpex Core as its predecessor but wrapped in the eTrax PLUS Hybrid coverstock, a blend of two-parts pearl and one-part solid.The placement of the TORQUE SPHERE just above the core's inner equator results in the lowest RG symmetrical core in Roto Grip history. This design also increases the differential, leading to more overall ball motion and reduced pin deflection. In simple terms, it delivers explosive power and excellent pin carry, regardless of your rev rate.Our eTrax PLUS Hybrid Coverstock combines the best of pearl and solid materials, resulting in the right balance of control and explosiveness. This ball is engineered to deliver impressive performance and consistently knock down pins.With the Torpex Core and TORQUE SPHERE Technology, the goal was to create a coverstock that not only complements the TNT but also enhances the entire Roto Grip product line. The aim was for explosive performance, and this was achieved by crafting this 2-part pearl and 1-part solid concoction from eTrax PLUS material.

The TNT Infused is Roto Grips newest piece in the HP3 line. This ball provides excellent mid lane read with its big core found in the original TNT as well. The pearl cover on this piece makes it sharp enough on the back end to get through the pins with ease, but does not want to go through with too much angle and 9 pin. I find this ball blends out wet/dry or over under really well. I find this ball very useful on sport due to its slower ball motion, making it more useful on low volume fresh sport patterns. Bowl up a Storm!!

Roto Grip TNT Infused Cover: eTrax Plus Hybrid Reactive Core: Torpex Core RG: 2.47 RG. Diff.: 0.052 Finish: Reacta Gloss Roto Grip’s new TNT Infused is a Hybrid (2/3 Pearl, 1/3 Solid) Symmetrical piece that is good for Medium-Heavy Volume Patterns. PAP is 5 5/16 R 1 3/16 Up. Rev Rate: 400. Speed: 16.5. Drilled this piece with the Pin above the bridge, CG kicked out 1” from the palm. I threw this piece on a fresh 42’ House pattern. Out of Box ball motion was smooth through the fronts with a hockey stick Motion on the backend. I compared this piece to the Roto Grip Magic Gem (Asym), Clone (Asym), and Hustle USA (Sym). Magic Gem 2-2 Left but started early in the mids with a smooth backend. Clone was similar line as the Magic Gem but a few more on the backend. Hustle USA was 3-3 Right and is smoother on the backend. This piece fits between the Magic Gem and the Hustle USA.

Comments
The TNT Infused is our new Hybrid from the TNT Line. With the Torpex Core and eTrax Hybrid Cover, it really digs into the lane like the original TNT. Comparing it to my Zen and weaker asymmetrics, this ball still out curves then all. Never struggles to get back from whatever angle you can think. This ball is a monster!

SPI WEBSITE:
Length and forgiveness. Now go ahead and say that again with us out loud, length and forgiveness. That was the philosophy we used in creating the latest installment of the TNT Series of balls – TNT Infused. Just like the original TNT before it, we use the term “benchmark” to describe our latest masterpiece of destruction. Armed with the same Torpex Core, we opted this go around to wrap that explosive core with our newly formulated pin-piercing shell – eTrax PLUS Hybrid. This version is the synergistic blend of 2-parts pearl / 1-part solid. So, if you are in the market for an explosive energy release through the pin deck, then you my friend have come to the right place.

Review
Roto Grip has infused the TNT with a Hybrid Reactive Coverstock wrapped around the Torpex symmetric core making this ball clean through the fronts and very angular on the backends. The TNT Infused has an RG of 2.47 and differential of 0.052 with a cover that’s two parts pearl and one part solid giving it an explosive reaction and powerful pin carry. This ball is great on medium oil patterns and will perform at a high level in the track area and into the fourth arrow without any loss of ball reaction. Put your favorite pin up layout on the TNT Infused and you will not be disappointed. This ball is a must have for league and tournament bowlers. Now available for order at your local pro shop!

I drilled up my ROTO GRIP TNT INFUSED with my standard layout of 4.5 x 4.5 x 2.5. This puts the pin close to the middle of my grip line but a good inch and a half above the fingers with a small CG kick out. I hit the surface with 1000 then lite Storm Rough Edge which is my new go to on factory Reacta Gloss surfaces.

I put this one up with my pearl balls that I use when I see a medium to medium dry pattern or house on burnt panels. I threw it against my EXOTIC GEM, newer JOURNEY, and VIRTUAL ENERGY BLACKOUT. Compared right away to these, the TNT INFUSED was longer thru the fronts than the EXOTIC and VEB. The JOURNEY was close with the same surface on it. The EXOTIC and VEB were close to the same ball motion as the INFUSED. The INFUSED started its move towards the pocket just a little later than both of those. Compared to the JOURNEY, it is much earlier and stronger down lane. These two should play off each other well.

Put this one in your bag if your looking for a stronger medium piece that has a slightly later motion than the big asym pearls do. Or if you want to get a 1-2 punch, grab a JOURNEY also.

Layout: 45 x 4 5/8 x 35
I had success using the original TNT on tougher patterns, but it was too strong and rolled too early for me to be able to use it on the house shots that I see.  The TNT Infused is the absolute opposite; it is clean through the fronts but has an a bunch of backend flip.  Due to this, it is a killer on the medium oil house shots that I usually see.  Even though I would characterize the backend as being a bit flippy, it is still controllable.  It is strong enough overall to use to begin with, but has plenty of pop downlane as I need to move left throughout the night.  If I need something that can handle a bit more oil than the Infused, I change to the Sublime or the Magic Gem.
