RST X-1

Tour players naturally tend to migrate to those balls that offer more core torque and continuous motion down lane with minimal deflection through the pins. It was that logic that led to the development and creation of the all-new Roto Star Tour™ Core—designed for Tour level players and those who aspire to score like them..

RST Core

Professional bowlers like to see continuous motion down lane with minimal deflection as the ball enters the pocket due to their rev rates usually being on the higher side. This logic was the basis of development by the R&D team as they looked to create a core that would maintain dynamics after drilling in order to maintain a higher level of core torque down lane. The larger mass at the base of the core does indeed create that. Especially since when drilled, the thumbhole will always end up in the void area not really affect the bottom mass of the core. Thus, making this core a “Tour Level” type core design better known as the Roto Star Tour Core (RST™ Core).




MicroTrax™ Coverstock

The MicroTrax (Micro Nanoparticle Traction) Coverstock offers the optimum balance of midlane traction and responsiveness to friction thanks the blend of nanoparticles throughout the coverstock. This formulation maintains its surface profile texture longer to ensure you get maximum performance while displacing oil at an above average rate compared to other coverstock materials on the market today.

Engineered for Medium/Heavy to Heavy Oil Conditions

Roto Grip RST X1
I really like this ball. I have had it for about 6 weeks after taking about 2 years off. I am not bowling leagues as of now but bowling some small sweepers etc and this is a good ball early in the block for me....The RSTX1 doesn't seem to bleed off energy once it comes off the spot it continues. The more time I put in with this one the better I like it.

Review:
The new Roto Grip RST X-1 is a very unique ball. The old school look of color and logo are very appealing. The ball is very aggressive but seems to save most of its motion for the back end of the lane where the X-1 drives hard. The Roto X-1 fits between my Rubicon and UFO in total hook. This new X-1 goes a bit further than my UFO but still grabs in oil due to the 3000 sanded strong cover. The X-1 revs up in the mid lane and finishes with a hard hit. I have rolled this ball a lot and it does not lane shine easily. To me the finish acts stronger than the 3000 stated. The X-1 is low maintenance and is easy to clean with any Storm spray or wipe. I am very happy with the hit and motion of this ball. I have ran into some conditions where it reads too early and starts to leave weak 10’s but if you more into the oil you are right back slapping the corners out. I have been getting away with good carry on some not so great shots. This ball works well on flatter patterns or modified house shots.
This ball started out as a slow mover in my shop but as more people got them the more demand went up, even with the Proton in the mix of offerings. Both balls have sold very well. I think this ball will be at our next Match Maker Demo and I’m sure it will impress some people.

Summary:
The RST X-1 has a strong unique ball motion.
The Ball has a very strong back end move for a dull ball.
The X-1 rolls great on flatter conditions.
This is a great add to a tournament arsenal.
