Professional bowlers on tour, and those that want to bowl like them, like bowling balls that offer more hook and continuous down lane motion while driving through the pins. It is this type of bowler that the Roto Grip RST X-1 hybrid reactive bowling ball was designed for. This high-performance asymmetrical ball has a core that produces consistent core torque as well as energy transfer down lane. This RST (Roto Star Tour) core is wrapped with a versatile MicroTrax Hybrid coverstock which generates ideal responsiveness on both oil and friction.

Before the release of this ball the talk was how similar to the Physix this ball is. When I heard that my ears perked up and I was excited to see it go down the lane. After seeing a MatchMaker RST go down the lane, yes the shape of the ball motion is the same as the Physix and I knew I needed to give this ball a try.

When comparing the two (Physix vs RST) the Physix is an earlier motion for me compared to the RST. The hybrid cover on the RST gives me a cleaner reaction through the fronts giving the ball more length than the Physix but has the same response or shape (harder and quicker) off the dry as the Physix and and both are continuous through the pins.

This ball fits between the original Physix and Rubicon for me when comparing the Asymmetric cores in the Storm family. I tested it on 40í Red Square and it rolled great where the Rubicon was too forward and didnít give me enough shape at the end of the pattern to make it to the pocket.

Layout 45 x 5 x 40. I left this one box finish which is 3000 abr and have been touching this up with the 3000 pad.

My intent was to drill this and see what it looked like before adding a 2nd or 3rd one to the bag. So far it has been hard to describe where it fits and not in a bad way. It is not a PROTON PHYSIX, but is has more motion than my RUBICON. It is very readable and predictable and I have been using it on mostly medium/long-long patterns in the 40-44 foot range. If I am on the slicker side of the spectrum, I touch it with the 3000 pad and close my angles down. It also works for me when I need to open up my angles slightly more. If I have to really open them up, then I work in my NUCLEAR CELL and ball down from that to a AXIOM PEARL.

The RST X-1 looks like a great shape that anyone who isn't afraid to drill a 2nd or 3rd companion ball would want to do it with this release. The cover looks like it might be more on the solid side vs pearl and that may be what is dictating the motion which is a strong arc type reaction without over snap.

Roto Grip RST X-1
Cover: MicroTrax Hybrid Reactive
Core: RST (Roto Star Tour) Core
Layout: 70 x 5 1/4 x 30

Roto Grip has made some great balls of late. The Rubicon and Rubicon UC2 are two of my favorites. Both the Rubicon and UC2 are really responsive downlane especially for asymmetrical balls. With the RST X-1, I wasnít sure exactly where it would fit in but I was hopeful that if I put the same layout on it as I have on my Rubicon and UC2, I would get a nice compliment. Bingo. For me, the RST X-1 has a lot more control than either Rubicon. The cover seems to bleed a bit of the energy going down the lane and I get a very controlled ďtourĒ type breakpoint. I wouldnít consider the RST X-1 angular in any way for me. In fact, I kind of see a trick layout type reaction with a standard pin up drill, which makes its window of use much longer. I have thrown the RST X-1 on sport patterns and house and it has a place in both worlds.

The new RST-X1 is the newest HP4 ball introduced to the roto grip line. I'd put this ball in between the ufo and the rubicon. To me this ball for being a big asymmetric hybrid gets through the fronts reads the mids and had a lot of pop off the spot. It kind of reminds me of an Original Physix from storm. If you're looking for a dull asymmetrical bowling ball that is great left to right this is the ball for you! Go to your local pro shop and get one of these you won't be sorry!

COMMENTS

Likes: The new Roto Grip RST X1 provides a unique shape to the Roto Grip line. Its an extremely aggressive ball that does not pick up too quick and slow down. I found out very quickly that the RST needs volume to be really effective. On the typical league pattern it was a little too aggressive for what i like to do but it was not unusuable. I compared the RST to one of my favorite asyms of all time the Physix. It alittle earlier than the Physix and much much more overall. The Physix shaped the lane just a tad more simply because it was alittle cleaner. After a small surface tweak the RST, put it at 4000, the RST began to be very similar to the Physix in motion but was still alot more overall.

Roto Grip RST X-1 Ball Review by PJ Haggerty

The Roto Grip RST X-1 is the newest addition to the HP4 line and itís special.  With an RG of 2.53 and a differential of .053, that tells me this ball will be a bit cleaner than the UFO and Proton, but would be a nice compliment to those as well.  Iíve had success on multiple surfaces and patterns with the RST and I think it fills a nice spot in my bag.  Also, with the MicroTrax (hybrid) coverstock, this provides a bit more length and a quicker response time than a traditional asymmetrical ball. 

Iíve drilled two RSTís so far and really like both.  My favorite one is mapped out as 5 ľ x 4 x 50.  Iíve had the most success when the bigger asymmetrical balls slow down too much and I need a cleaner ball with a relatively quick response time.  Also, my angles have been further open when Iíve struck the most with the RST.  Iíve had a tougher time playing straight due to it being almost too clean.  Overall, I love the motion the RST provides and it compliments so much of the lineup so well.

If you need a ball to use when your UFO or Proton Physix start to bog down, the RST X-1 could be a great ball to drill!
