Additional product information:

Given the continued success of the RST™ X-1, we knew the next ball in the series using the Roto Star Tour Core was going to need a special coverstock wrapped around it as well. So, after countless tests involving multiple players of different styles, we determined that the eTrax™ pearl material gave us the type of reaction we were looking for, but we wanted something a little more while still using that same chemistry. So, the R&D team went to work changing the ratios and other variables until we settled in on the NEW eTrax™ PLUS Pearl Reactive formula that provides a larger footprint throughout the entire lane without reducing the responsiveness to friction down lane. Creating yet another viable pearlized coverstock option for the Roto Grip family of balls.
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).

    Zach Shoff 900 Global Staff Member BowlerMAXX Pro Shop Staff Member Right-Handed Rev Rate: 350 Speed: 15mph PAP: 4 Over & 3/4 Up You need a ball that is strong in the mid-lane but also come off the spot hard. This is how I describe this ball. With my slower ball speed, I must start deep to be able to play with this ball on a standard house shot but when I compete on a challenge/sport shot that is heavy oil this ball is coming with me. It just doesn’t stop turning. For a ball that picks up early it never loses energy down lane when entering the pocket. Also, in my bag there is no ball that throws pins around more than this ball!

    I loved my RSTx1 for a big asymmetrical was super excited for the pearl and was not disappointed in the Rstx2. This ball takes over where the RSTX1 leaves off. When the RSTX1 slows up and losses that kick and drive down land que the RSTX2. For a asymmetrical pearl this ball gets down lane clean and motion in the backend is quick but controllable loving this new ball definite fit in my bag

    Clean, Clean and ... CLEAN!

    The RST X2 is by far the cleanest asym pearl I have ever thrown. As such, the X2 really bridges the gap nicely between our stronger pearl symmetrical balls and our stronger slower asym pearl balls. For instance, if you have a Halo Pearl or a Parallax Effect that just wont corner hard enough, but your Idol Pearl or Axiom Pearl isn't quite strong enough, the X2 will be perfect. I personally have my X2 at box finish because it rolls well for me, but I have sanded it significantly on higher friction surfaces where we were bowling on longer patterns. The combination of the clean cover and surface allowed me to clear the front on the higher friction surface, but didn't miss the midlane because of the surface of the cover. It's an all around versatile piece that all players should have in their bag.

    Roto Grip RST- X-2

    Posted by Brian Watson on Nov 17th 2021

    The new ball in the HP4 Line from Roto Grip is the RST-X2 . The X-1 has been a very good ball and very successful in the bowling market. So Utah came out with the pearl version. I drilled mine 5.25.x5.x4.5 pin down. With the eTrax PLUS Pearl Reactive, man that ball is clean! For an asymmetrical ball X-2 gets down the lane very easily. With that being said it does store some energy and has a good response to the friction. But with the RST Core its still controllable motion and not as angular as say a UC2. So if your backends are pretty clean and the UC2 is a little too sharp then X-2 would be a good ball to use. Roto grip has some very good Asymmetrical's in the line today with each one providing a different shape. Brian Watson Pro Shop Staff PAP - 4 1/8 Speed -16-17 Tilt - 17 RPM - 400 Modify message

    The great results of the RST X-2

Differential •.016 Layout • 45 x 4.25 x 40 Tester PAP = 4 ½ R x 3/8 D • Tester Axis Tilt = 12° •Testers Rev Rate = 325 Test pattern = 42' THS (Typical House Shot) • Modified, Kegel Stone Street The new RST X-2 from Roto Grip really piqued my curiosity, and I was excited to see how it would perform for me. It has the proven RST (Roto Star Core) found in the RST-X1 combined with an all-new eTrax Plus Pearl Reactive coverstock. This combination delivered some exciting results. So let's take a closer look at how it performed on a THS. The RST core found in the RST X-2 is a strong asymmetric without being too overbearing. I like this core's ability to take the force off your hand and turn it into a strong, hard rolling powerhouse down the lane. Some asymmetric cores tend to be lazy and lose their luster when turning off the pattern, but the RST core stands up briskly and rolls with a firm authority that you can count on. Further, the RST core gave me confidence with its ability to explode at the pins without much deflection. Finally, I like how this core continued its rugged rolling toughness until it was through the deck! At first, the new eTrax Plus Pearl reactive cover was a bit of a struggle for me. It has a very clean look to it and gets further down the lane than the RST X-1. But, on fresh oil, with my low-rev style, I found it a bit of a struggle getting the eTrax cover to react to my liking. So, having too much skid and not enough roll, I decided to cut this cover with a 2000-grit Abralon without polish. Again, for my high-speed/low-rev style, this adjustment made the eTrax cover much easier to control on fresh oil. As the pattern broke down later in the night, I found that the 2000 grit alteration made this cover dynamite! By late night, I was able to move in with confidence and control. The eTrax Pearl reactive cover makes the RST X-2 an excellent choice when conditions change, and the shim line forces you to move deep inside. As for surface adjustments with the RST X-2, I strongly suggest tweaking the surface to dial in the exact motion you want. This cover leaves plenty of room for a variety of bowlers and comes alive with surface adjustments. In closing, I found the RST X-2 to be a clean, sharp-looking, and hard-rolling ball. The RST X-2 would pair well in any arsenal with an RST X-1, Rubicon, or a strong early-night ball. With the eTrax Plus Pearl cover's flexibility, the RST X-2 is the perfect choice for when you need to dial in that particular motion when nothing else seems to work as the conditions break down. Finally, the RST X-2 is an excellent choice for a classic-style, low rev bowler on a THS. So, ask your local Pro Shop operator today about this Roto Grip RST X-2 and see for yourself why you should "own it!" Rick Klimowicz Storm Products Pro Shop Staff Roll the Ball Pro shop Penndel, Pa

    Roto Grip RST X-2 Ball Review

    Posted by Patrick Keiffer on Oct 25th 2021

    The Roto Grip RST X-2 features a brand new ETRAX Plus Pearl reactive coverstock with the Roto Star Asymmetric Core. The X-2 has a medium RG of 2.53 a high differential of 0.053 and a low intermediate differential of 0.016. To bring this all together, the eTrax coverstock is the most responsive coverstock down lane created to date by Roto Grip combined with the Roto Star core gives you a more aggressive and responsive than the Rubicon UC2 or the Idol Synergy. The X-2 is going to give you a true reactive response on a variety of conditions by easily clearing the front of the lane while responding to the friction downlane. The layout chosen was a 15 x 3 3/4 by 45 which will give the ball a smooth reaction shape which changes direction the least, best when controlling the pocket and on wet/dry patterns we see on house shots or sport when they become cliffed. I did a ball comparison to the Roto Grip RST X-1, Storm Dark Code and 900 Global Zen on a 42 ft house shot pattern at Pin Station Lanes. First up is the Roto Grip RST X-1. The RST X-1 with the same core but with the Microtrax hybrid coverstock gives you that blend of continuous smooth motion through the midlane then you see how the Roto Star Tour asymmetric core comes together with a very round shape dowlane. The X-2 compared to the X-1 you will see its more continuous through the midlane but has more pop on the backend then the X-1. So basically when you start leaving the flat 10 switch to the RST X-2 to get the 10 out. Next is the Storm Dark Code, the Dark Code has REX Coverstock which is a combination of the NEX with R2S. The Storm Dark Code is very smooth and continuous through the heads and midlane and saves all of its energy for the backend. The RST X-2 is stronger than the dark code by several boards. The last ball in the comparison portion of the video is the 900 Global Zen. The 900 Global Zen featuring the Meditate core is is continuous and smooth through the fronts but when its sees friction it takes off. You will see here I kept on moving 4 and 2 left to see which ball out hooks the other and the Zen won once I got really deep inside. But this comparison shows you just how strong and versatile both balls are. In my bag, Zen, RST X-1, the X-2, the Storm Dark Code, then the Hyroad Pearl.

    RST X-2. The perfect compliment to the popular RTS X-1. Featuring the new eTrax PLUS Pearl cover wrapped around the RST Core, the RST X-2 gives you extra length with a more angular entry to the pocket. This is the perfect ball for when the front part of the lane isn’t fresh, or you are looking to move left as the lanes break down while still needing overall hook and a strong ball. The RST X-2 is very strong when it makes it’s transition down lane, so its better suited for patterns and conditions that have slightly more oil or length of oil on the lane.

    I had a lot of success with the X1. For me I kind of saw the X1 as an asymmetrical Phaze2. Similarly I kind of see the RST-X2 as an Asymmetrical Phaze3. I see this ball being cleaner than any other asymmetrical pearl across the brands with strong/controllable movement down lane. I actually wasn’t a huge fan of this ball out of the box, BUT when I cracked the cover with a 3000 pad, this ball came to life. The straight pearl cover with no additives on the X2 is great for higher friction surfaces like wood or HPL’s.
