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).

    The RST-X1 has been a staple in my current league bag as well as tournament. It’s been lights out on most patterns for me. I’m very happy that they made a Pearl Reactive known as the RST-X2. Sometimes I have to shy away from asymmetric bowling balls because they tend to get a little to tumbley for me and roll out. This series allows me to stay confident with my shots along with moving left. The RST-X2 is going to be able to get you farther down lane then the X1 but coming hard off the spot allowing you to still get great carry. This ball is going to be my house shot killer I can tell you that much. I always start with my X1 so now I can transition to this when the ball picks up a bit to early.

    After instantly falling in love with my RST X-1 it was a no brainer punching up the RST X-2. This is the big asymmetrical pearl i was looking for in the bag. This ball gets through the mids with snap of the spot. Being that it is asymmetrical when you miss a little in the ball still digs in and drives through the pocket. If you're looking for a house shot killer look no further than the RST X-2. Get to your local pro shop and put your favorite layout on this and you will be off to the races.

    RST X-2

    You want to talk about a ball with some serious angle?!?! Roto Grip introducing the brand new RST-X2. The RST-X2 is the newest addition to the RST Line. This time, it’s a asymmetrical pearl. The X2 features the same core found in the RST-X1 only wrapped with the eTrac Pearl Reactive. This ball is very clean throughout the lane and has absolutely ridiculous downlane motion. For me, the X1 and I didn’t get along very well; so I really didn’t know what to expect from this one. Man, I WAS BLOWN AWAY. This ball is a perfect compliment to my UC2, which I absolutely love! When my UC2 is too clean and not enough donwlane, the X2 gets the job down and has even more backend than the UC2. This is a perfect 1-2 punch when I need bigger/cleaner option for heavier oil patterns from inside. This ball is also, in my opinion a house shot killer. Stand left (if you’re right handed) and throw right and watch this thing do a U Turn! You don’t want to miss out on this one. Go to your local Storm Vip Pro Shop and get your’s today!

    Roto Grip RST X-2 Ball Review

    Ball Specs: Core: Roto Star Tour Cover: eTrax Plus Pearl Reactive RG: 2.53 Diff: .053 PSA: .016 Bowler Specs: Speed: 15.5 MPH Rev Rate: 300 RPM PAP: 5 ⅜ over 1 ¼ up Video ball review: When I decided to add the RST X-2 to the arsenal I wasn’t sure whether to drill it pin up or pin down. I already had a strong Asymmetrical pearl, the Dark Code drilled pin up and with my axis rotation the closest to a pin down drilling I can use without rolling over the thumb is the Reality with pin in the ring. So I decided to go with a dual angle layout of: 40 x 51/2 x40. This gives me a pin down type of reaction. For me this ball does need friction down the lane to help get it to the pocket and with this layout I can stay in the friction longer and have the stronger asymmetrical core help. The pearl cover on this ball makes it very clean through the heads and very sharp or angular off the dry. With my firmer speed and lower rev rate it shoots past the midlane on most house shots I’ve tried to use it on. For me so far I have had more success using this ball during the later games of a tournament on a 42’ pattern. This will be a ball I have for the tournament bag and not the league bag.

    RST-X2 Ball Review

    Hey everyone, I'm back with another ball review, and this time it's for the Roto Grip RST-X2 and in 15 pounds this ball is wrapped in the eTrax PLUS Pearl coverstock and comes at 1500-grit polish with an RG of 2.53, Diff of .053 and A MB of .016 with a layout of 4X4X2 It is very easy to say how pleased I am with this ball. If you had thrown the original RST-X1 the X2 is everything that ball is and with the pearl cover you get that clean motion in the heads. A great ball for that medium to heavy oil condition. The X1 and X2 are a great combo, and I can see where both balls will fit within the same bag.

    X2 - Excellent follow up

    Roto Grip RST X*2 - Layout: 50 x 7 x 50 - 1500 grit polished Ball test conditions: Practiced on 44ft THS on SPL and 46ft THS on older HPL The next evolution in ASY cores have gotten a new and exciting addition -- The RST X*2 !!! After drilling two different laid out RST X*1s, I leaned towards drilling a longer pin to PAP for the X*2. So with that approach to layout, surface of the panels and patterns, I went for my first ever 7 inch P2P layout. Well, the ball retained a huge amount of energy, super clean in the middle and near the end of the pattern and a sweet angle into the pocket with attacking the pattern with open and closed angles. I was skeptical that having a longer than 6 inch pin would cause the ball to not have any recovery, but it was surprisingly strong with a good strong reaction. The roll reminded me of the Hyper Cell with a little weaker reaction. Will be a great replacement for bowlers looking to replace the Hyper Cells, UC2s, or Idol Pearls.

    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.
