Roto Grip Tour Dynam-X Bowling Ball

The Ball rolls great the pour is good and it got here in no time at all

The Roto Grip Tour Dynam-X provides you control down lane when a bowling pattern may get tricky or requires control. Personally it is a great Game 1 ball for me. Go visit your local pro shop to order one today.

The new Roto Grip Tour Dynam-x features the Rondure Tour Core wrapped in Tour Trax solid reactive coverstock. At 15 pounds the ball has an RG of 2.47 with a differential of .026 and an intermediate differential of .010. I drilled this with the pin above the bridge. The Tour Dynam-x low differential will allow bowlers to keep their angles closed longer and play closer to the friction than most reactive balls would. This ball is a must have for tournament players as well as league bowlers. The Tour Dynam-x is very controllable for the tougher patterns as well as blending out the wet/dry house patterns. This is a heavy rolling ball which not only excels at going up the boards, but it also performs well when you need to open your angles a little bit. This is one of those balls that won’t wow you with overall hook or backend motion. All it does is give the bowler a consistent reaction with excellent pin carry, keeping you out of trouble and in the pocket striking longer!!

I am a higher speed, rev challenged 220-250ish, high tilt, high rotation, and super low track player. I drilled my Roto Grip Tour Dynam-x 5 5/16 x 3 x 2 and my axis point is 3 ¼ right and 7/8 up. The Roto Grip Tour Dynam-x is a small asymmetric solid reactive piece that I really like to use on short and medium volume patterns. The low Rg and small diff gives this ball medium- high flare potential when I need something to spin up fast, be clean, smooth, and controllable this is the ball to go to.

About Me 900 Global Staff Left Handed: High Rev High Speed Player Pap: - 47/8 +1 Rev Rate: +-500 Speed 17-18mph Layout: 4 ¾ X 3 ½ X 1 Ball Video: N/A Sneaky good and very predictable. I haven’t had a chance to throw the Tour Dynam-X very much before I had surgery. The Dynam-X was definitely stronger than I expected. I had heard different reviews on what this ball was supposed to be. I heard it was supposed to be strong and I also heard that it was supposed to be weak and roll more like urethane. Both of those reviews are correct. What I mean by this is the Dynam-X is a strong ball but has a roll like urethane. The reason I say it rolls like urethane is because of how early it picks up on the front part of the lane and starts reading the pattern and then gets down lane and breaks and has the nice strong controllable finish through the pins like urethane. No, I am not saying that this is taking the place of your urethane equipment because it’s not. What I am saying is the roll reminds me of a very, never seen before strong urethane ball. The Dynam-X hooks like a solid and is very controllable and hits like a tank. I truly believe that the Tour Dynam-X is going to be useful on all different types of patterns, be very versatile and shoul make your line up, I know it’s making mine.

Layout: 4 1/2 x 4 x 3 1/2 PAP: 5 1/8 x 7/8 Up Rev Rate: 315 Axis Tilt: 27 degrees Axis Rotation: 45 degrees I drilled my Tour Dynam-X 4.5 x 4 x 3.5 and I was really looking forward to throwing it. It has the Rondure Tour Core, which is a slightly modified version of the Rondure Core that was in all the Rubicon balls. The Rubicon Tour core has a slightly lower RG and intermediate differential, but a significantly reduced differential. I really wanted this to be a ball I could bail out to after the lanes get torn apart during league. My first reaction throwing the ball was “This ball HOOKS!” Needless to say, that’s not what I was expecting out of this ball. It took 7-10 games for it to really tame down and settle in, which has significantly reduced the amount of overall hook and has become much more of a control piece. I’m still not using it a lot on house shots, but it definitely makes the trip with me to any tournament I bowl in. https://youtu.be/Y5EB8kUTf_k?si=tyjwxsG7mtO6JuXv

Layout: 30 x 4 x 65 The Tour Dynam-X has a very unique ball reaction that, as intended, is best compared to the Storm IQ Tour. It is very smooth and predictable, though the added asymmetry gives it a touch more downlane kick. It does not pick up too early, and saves everything for the midlane. With surface, this ball is good on heavier or flatter fresh patterns. For me, the smooth arcing nature of this ball lends itself to being much better when straighter angles or a “down and in” line is needed. Once I have to move left, balls like a TNT Infused or Clone come around the corner better. I find that this ball is a great alternative to using urethane.

Bowler Stats: Speed: 15.5 MPH Rev Rate: 275 RPM Tilt: 3-5 degrees Axis Rotation: 60 degrees PAP: 5 ⅜ over 1 ¼ up Layout: 41/4 X43/4 X 2 VLS With the release of the Tour Dyman-X during the PBA 50 Season I was not sure how I would match up with the design of the Rondure core. After seeing the core numbers and it being a weaker asymmetrical core I decided to put a stronger layout on it rather than my normal one. I thought it may give me a urethane type of motion off the end of shorter patterns since I didn't have urethane as an option in my arsenal. Unfortunately I think I missed on the layout because it’s very confused on the house and sport patterns. The 41/4 inch pin placement gives me the proper length with the weaker core but the 43/4 mass placement doesn’t allow the ball to flare enough when it begins to read the dry at the end of the pattern. I used a similar drilling I would use on an !Q Tour solid since this ball was to be slightly stronger with the same type of ball motion. I changed the cover to 1000 abralon by hand and that helped it read the house pattern for my ball review video but as it shined up it still was confused. I plan to drill another one and change the mass bias placement in the VLS layout to 4 inches and so it will flare more to match my lower rev rate. Pete Dohan Storm Bowling Amateur Staff #StormNation

Tour Dynam-x It says it all in the name... Tour. This ball exceeds on tougher conditions like the pros see on tour, but don't get me wrong this bad boy also works wonders on a house shot. With is smooth, predictable, and very controlled motion you get an asymmetric shape with the continuation through the pins like a symmetrical core would.

Roto Grip Tour Dynam-X Layout: 4.5 x 5 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 Tour Dynam-X utilizes the Tour Trax solid coverstock and the Rondure weight block. My first thoughts are control and versatility. The Dynam-X is another option in that iQ Tour space. The Dynam-X can be thrown from straighter angles early and deeper angles later in the blocks. It will never be the ball to cover the most boards but can be thrown from left to right with modest board coverage. We had the Dynamix a touch stronger than the iQ Tour, which has to be the coverstock. The Tour Trax is a new generation solid coverstock that blends the trust-worthy Versatile Traction Control (VTC) coverstock from the Hustle line with some new additives to create a versatile bowling ball.
