Title: RST X-1
Post by: BallReviews-scodaddy21 on February 04, 2021, 03:24:35 PM
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 40’ Red Square and it rolled great where the Rubicon was too forward and didn’t 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 wasn’t 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 “tour” type breakpoint. I wouldn’t 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.
