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).

    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. Layout- 50x5x30 or 5x4x2 Balls that are currently in the bag: Zen- 50x4.25x65 UFO Alert-50x5x65 Dark Code- 50x4.25x65 Trend 2- 50x5x30

    Roto Grip RSTX-2 50 x 4 x 70 This ball is absolutely incredible! In my opinion this is one of the most special balls that has come out this year! It is one of the cleanest balls we make and is sideways off the spot. For me, I've struggled late block was balls being a little too rolly off of the spot. This ball has more than exceeded my expectations. My favorite ball is the Zen, this ball is the perfect compliment! It gets down the lane easier and further and comes off of it just as hard! This is one of the 2 best balls on the market, everyone needs this ball!

    RST X2 versatile pearl

    Posted by Brian Eger on Oct 18th 2021

    Style – stroker Speed – 14 MPH Layout – 5.5 x 3.5 x 2.75 PAP 5 7/8 over and 3/8 up Condition – house patterns Surfaces – HPL and Pro Lane A great deal of anticipation for this release from my end. Had a tremendous amount of success with the RST X1. Loved the shape the cover and core provided on the X1. The same core added to the eTrax Pearl cover provides another super continuous shape for my ball roll. The ball for me is receptive to hand position changes and should appeal to a wide range of bowling styles on multiple patterns. Ball was super clean through the fronts on a worn HPL surface with a big puddle in the middle. As the night progressed, I had to get out of that portion of the lane and didn’t have enough hand to stay in the puddle and get it around the corner. I don’t think higher rev rates would have any trouble getting it to turn the corner. On the newer Pro Lane surface, it was nice on the fresh until carry-down hit. While I could still get the ball to the pocket, I left several 10 pins. Again, my rev rate wasn’t enough to get it through the pins. For houses with lower volume patterns, I think pretty much anyone could use this ball. Higher volume houses you’d need to wait until the lanes transition before getting into this ball. Lower rev rate players might have issues getting it to pick up and higher rev players might have issues controlling the break point on fresh conditions. As with all bowling balls there is a time and place to use each one of them. For me, it’s just going to be after the lanes transition some. But this ball is versatile enough to keep you in play for longer windows and should be a nice addition to any bowlers bag.

    RST X-2 review

    Posted by Dave Klaas on Oct 11th 2021

    60 x 4 1/2 x 30 on the layout Axis point is 4 7/16 over and 3/8 up. Revrate in the upper 300s, ball speed between 15 and 16 mph. I typically like to start at 15 on a typical house shot and migrate in from there. Initial reaction...Roto has been doing a great job with color combos. The color of this ball pops off the shelf and looks very nice going down the lane! On to the review: I drilled a UFO Alert with a weaker/smoother layout, which works really well for me on the fresh at my home center but once the snow starts flying, I needed something with similar length but just a touch sharper off the spot. This ball does exactly that! Starting with the UFO Alert at 15 board at the arrows, it was laboring entering the pocket. I switched to this bad boy and I was ripping the 10 out time after time. Going left, it just seemed to pick up more and more steam! Sometimes, getting too far left with pearls leads to over/under looks but I was able to use this for 3 straight games during league with zero lack of performance. If you are looking for something to get around the corner a little harder, this ball will certainly do the trick. Go out and drill one today!

    RST X-2

    Posted by William Tefft on Oct 6th 2021

    Ball Specs: Roto Grip RST X-2 Cover: 1500 Polished e-Trax™ PLUS Pearl Reactive Weight Block: RST™ Core (Asymmetrical) Color: Tanzanite Review: The RST X-2 is probably the prettiest ball I have seen in a long time. The ball simply looks stunning sitting in your bag or going down the lane. When I initially saw the ball I thought of the Hyroad Peal, based off looks alone. After I threw the ball I knew that this was going to be a completely different ball than the Hyroad Pearl. Pearl bowling balls sometimes make me nervous because of their strong backend motions, when I throw the RST X-2 I am not nervous what so ever. This ball is clean through the fronts and has a strong continuous motion on the backend. If you are a tournament bowler that is looking for fill that void in your bag or just a casual league bowler that likes to see the ball have a strong motion you are going to enjoy this ball.

    RST-X2 Review

    Posted by Glenn Wendel on Oct 3rd 2021

    Ball Specs: Roto RST X-2 E-Trax Pearl Reactive Asymmetric RST Core Finish grit 1500 Polished Bowler Specs: Right Hand. PAP 5” Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at release 17 Review: The new Roto Grip RST X-2 is awesome! I try not to overstate anything in my reviews but this ball is just so good! The RST-X2 is the strongest and most angular polished ball I have rolled probably ever. The look of the ball is very nice also. This ball is much stronger than my UFO Alert and more aggressive on the back end. The carry and drive through the pins is excellent. This ball took a while to gain momentum at our shop but as the word got out and more went down the lane the demand is steadily growing. I look forward to seeing the ball in multiple hands at our upcoming Ball Demo. I have a feeling I better stock up. I have taken the RST-X2 to multiple houses and shots and the results have been good everywhere. This ball will work on a house and a sport shot easily as long as there is a decent amount of oil. I do not get any squirt on oil with this ball due to the strong cover enhancements Roto Grip has made. Overall I am very excited to be rolling this ball and expect some big numbers with it. Summary: The RST X-2 is Strong and Angular. The Ball has great back end and hit. The X-2 is a fun ball to roll. This ball seems to work for many different styles of play.

    RST X-2 The Moon!

    Posted by Shaun Ciesielski on Oct 3rd 2021

    The Roto Grip RST-X2 is the perfect complement to the original RST X-1. X-1 was your earlier roll for oil, X-2 is the skid flip version. My X-1 was my benchmark go to ball, now I have something that I can go to when the fronts dry up and need the length with same backend motion. I drilled mine 5.5x4x2. I just love the length and backend motion from the ETrax+ pearl reactive coverstock. This HP4 line ball is an asymmetric ball with the RST X-1 core. This was the same motion feel of the X-1 just later downlane, strong yet predictable motion. Compared to the UFO Alert its more length and more angle. Hitting Power is great like every Roto Grip Ball I’ve thrown. I found the best line to play is stand left and just throw right. My PAP is 5-1/8 and 1/8 up. Usually around 15-16mph, I’d probably be classified between a tweener and a cranker.
