The new Roto Grip Tour Dynam-x brings a brand new core and coverstock combination that is a completely new ball reaction in the Roto Grip Lineup!  This is the IQ Tour for Roto Grip but potentially better?!  A modified version of the Rondure Core was brought in here with half the differential as the original for a stronger front of lane move.  What's also great about this ball is its control and predictability.  It reminds me of a urethane ball that is all resin.  This ball is going to be great for harder conditions or where control is an absolute must.  For the normal typical house pattern, this ball would be best on the fresh for lanes that tend to hook a little more than typical or for the down and in player.  This ball definitely favors straighter angles over opening up the lane.  If you are a player looking to find a ball to be up the lane with or looking for your next sport pattern ball, than look no further. 

I was able to test this ball on the Kegel Alcatraz Oil pattern which is 38ft in length with a 2:1 ratio.  What I found on this ball was with my ball speed, the 2000 abralon factory surface was just a little too clean for the pattern I was bowling on.  It gave me a little too much length and not enough down lane reaction.  When I altered the surface to 1000 abralon, I got a much stronger footprint on the lane and it gave me more of the ball reaction I was expecting out of it.  It is a ball definitely designed for the fresh as it doesn't flare a lot.  At the 1000 abralon surface, I was able to throw the ball a little bit more left to right but due to its controllable nature, it didn't go through the pins as strong as I wanted.  I would say this ball would be more ideal for medium to shorter oil patterns and where control is needed.  All tournament bowlers should have this ball in their bag as a staple benchmark ball where urethane is too early and smooth and stronger resin balls are too much hook.  This will fall right in between those two types of balls.  Don't be afraid to add more surface to this ball to get a stronger overall shape.

Review:
The ball may be designed for the “Tour Player” but I can assure you this ball creates versatility for all levels of bowlers. If you are a fan of the Rubicon series, you are really going to enjoy throwing this ball. The same core that was first introduced in the Rubicon series is back and is now modified to create a different shape that many tournament bowlers have been looking for. When I first threw this ball I got the initial thought of this being an IQ Tour if it was symmetric. This is one of those bowling balls that will quickly become a staple in all bowlers’ bags. If you are looking for that asymmetric roll without wanting to break the bank the Tour Dynam-X is a great option. Make sure you pick yours up!

The Tour Dyman-X is one the newest balls in the Roto Grip catalog. It features the new mild-asymmetric Rondure Tour Core. It has a Low RG, Low Differential, Mild int diff. This ball is going to be similar to an IQ tour shape but a little earlier and smoother down lane. The flare is very low and tight, almost as if you were throwing urethane with a resin cover. This ball is going to let you control the lanes, especially the backends.

Compared to the Tnt, the TDX seems a touch weaker and is longer but shapes similar. I would have the TDX sitting below the TnT. The TnT was early for me and gave me issues due to the cover strength. The TDX will give you more length and with the mild asym, it will still give you shape down lane.

Compared to the P2, the TDX would be a ball down from the P2 as well. The P2 was much earlier and quicker off the friction, for me. The TDX would be a good ball to transition to when the P2 is starting to read the lanes too early or you need something with a bit more control.

The Tour Dynam-x is Roto Grip's next installment in their HP3 line. This piece, like the Rubicon is unique because it is an asymmetric ball in a lower line. This ball for me, is the definition to a beefed up IQ Tour Solid. While it is a tad stronger overall, it shows that same controllable motion off  during the entirety of it's path. It is a true middle of the bag ball that will keep you in the zone on most patterns, and tends to be the first ball out of the bag. I could see this ball being very versatile and is definitely recommended for the majority of bowlers, because it is a ball reaction almost no one could pass up. Get yours August 18th and Bowl Up a Storm!!!

Roto Grip has added a Tour piece to the HP3 Line. By modifying the Rondure core that was featured in the Rubicon series and pairing it with the new Tourtrax cover, they've created a ball unique to the brand, and to the market. The mild asymmetry of the Rondure Tour core creates a motion dynamic that is unique even from other Tour balls like the !Q Tour series.

I tested the Tour DynamX on the house pattern in my home center. We have a longer, heavier house pattern but very cliffed. I found the Tour DynamX most useful when I got very close to the friction, but still loaded up on the ball a bit. It was very Urethane-esque, where it wanted to read early and layoff down-lane. This pattern is not where I would choose to throw a ball like that normally because of how tight they are down-lane. However the higher ratio of this pattern made so that I could jam the ball into the friction early enough and create angle and actually took a little of the over-under away.

I also threw the Tour DynamX in another house I was visiting for a league sweeper. This house has very quick back-ends, and I tend to struggle there because of my lower ball speed This was where I really saw the unique advantage that the Tour DynamX can provide. Where I might use urethane on a similar condition, it often makes the lanes really tricky as they transition, with most modern urethanes flaring enough to pick up in the front of lane oil, but really causing it to push into the back-end. The result being a constant need to manipulate the shape as the lanes transition and even trickier; finding the correct ball to move into when the lanes transition. The Tour DynamX gives you all of the benefit of urethane type motion without the biggest drawback. The ball going down this part of the lane with a reactive cover actually makes the lanes better for the equipment you transition to.

I would recommend the Tour DynamX for everyone's tournament bag. It's also an incredibly useful piece in houses with quicker back-ends and for very rev-dominant bowlers. It takes well to hand position changes which also sets it apart from urethane as you can stay in it longer without losing carry.
