Additional product information:

Formulated for ALL bowlers regardless of their style or their skill level. The latest installment in the RST Series provides WAY more mid-lane motion than the RST X-2, while still providing PLENTY of giddy up down lane. This version of MicroTrax™ Hybrid features nano particles throughout to provide the traction you need in oil, while its two parts pearl provide you the reaction you have come to know and love about the RST Series. So, whether you are a recent PBA Hall of Famer, or this is your very first high-end ball, the RST X-3 will provide unparalleled reaction time and time again.
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-3 Review by Luke Rosdahl

    The RST X-3 features the MicroTrax hybrid cover at a 4K Fast surface, and is 2 parts pearl and 1 part hybrid. The RST or Roto Star Tour core comes in at a 2.53 RG, a .053 differential, and a .016 intermediate differential in 15 pounds. The combination is fairly wild considering that the X3 shares absolutely no similarity with the X1, which had the exact same cover formula and was also a hybrid, but was 2 parts SOLID and 1 part PEARL rather than the other way around, and the difference on paper is completely negligible. The X1 was much longer, a bit sharper, and a rounder shape. The X3 is very heavy rolling, chuggy, and early, but also manages a lot of shape, so it’s a very strong ball that also covers a lot of boards. It’s somewhat directional though, so you have a lot of control over the shape. If you want it to stop and go forward, it will, and if you want to get it to chase the 7 pin off the deck (for righties), you can get it to do that too. The downside is that the combination of the extreme strength and shape doesn’t put it in play on many conditions for most bowlers. However, on the flip side, if you have trouble with getting ball motion and/or shape, if this ball doesn’t help you in the strength and power department, I don’t know what will.

    RST X-3

    RST X-3 Coverstock: Micro Trax Hybrid Reactive WeightBlock: Asymmetrical Finish: 4K Fast Color: Yellow/smoke/grape Review: Roto Grip continues to produce RST bowling balls that have proven they can keep up with everything else in the line. This ball on its own stands out just because of the color but once you throw it a couple times you will quickly fall in love with the shape that this ball makes. After throwing it and changing the finish a little I have concluded that this ball is a great step down from my Gem. I get a similar shape with better backend motion once the carry down starts to happen. I found this ball to be great first out of my bag on the league shot during out second shift leagues. Make sure you grab yours as soon as they are available. Will Tefft Roto Grip Staff Member #SquadRG

    Roto Grip RST-X3 Review

    The Roto Grip RST-X3 features the Micro Trak Hybrid Reactive cover, Roto Star Tour core, and comes at a 4-k fast finish. The X3 is the third ball in this line following the RST-X1 and RST-X2. Compared to both of those, the X3 feels like the strongest in the line and one of the strongest in the SPI catalog. The RST-X1 was strong but more of a controlled shape and the X2 is clean with more punch down lane. Now the X3 feels earlier and harder off the spot compared to those two balls. The shape is different as it gets the spot, goes left (like someone kicked it), and doesn't stop. The X3 forces me into the 4th/5th arrow on my house shot and sometimes it is just too much. I did get a chance to throw this ball on the challenge pattern "Great Wall of China/48ft" and it looked amazing. For me, this ball is going to require heavier oil and I think this ball will be good for speed dominant bowlers and lower revs players who need a ball that is going to hook. Tobias Myers #RotoGrip

    Roto Grip RST X3 Ball Review

    Roto Grips newest high performance bowling ball is the brand new RST X3! This RST features the MicroTrax Hybrid Coverstock wrapped around the RST Core (Roto Star Tour Core) My RST X3 is drilled pin over my bridge with the mass bias by my thumb! This RST with it being a hybrid is a smoother than the RST X2 but more downlane than the original RST X1! Sometimes the X1 is to early and the X2 is to quick downlane this is where the new X3 will come into play and fit that gap amazing! Definitely will be in my bag for the heavier lane conditions! Head over to your local Pro Shop and get yours 8/19/22

    RST X3 Review

    Layout: 30 x 4.5 x 30 Surface: 1000 Grit Abralon The new RST X3 has been great for me in the first week having the ball. Sport shot league and a PBA Regional has really given me great ball reactions to help me score well. I put it to 1000 grit abralon to give me a ball for the fresh that is cleaner then the Reality but can still dig into the midlane when there is more volume. Even though the RST X3 is a hybrid with two parts pearl, it does not act like a pearl type hybrid at all. Even at the box finish, the X3 hooks a lot sooner then the X2 and is more down lane then the X1. At the 1000 grit finish, it would be best used on heavier oil and longer oil patterns. Test Pattern: PBA Don Carter Pattern At 1000 grit abralon surface, I saw a lot of front hook and strong midlane read while still continuing well down lane. What I like the most about it, is how consistent the ball reaction is. Whether I am playing up the lane on the fresh or more left to right, I saw the same continuation which allowed me to stay using the ball for multiple games which for me is very tough for a 1000 grit ball. As the lanes broke down, I was able to play 4th arrow with ease as long as I projected the ball to the 2nd arrow. Throwing this ball up the lane wants to hook pretty soon which will make it a great fresh ball if you are in the market. House Pattern Test: At the 4k fast finish surface, this ball should be really good on the fresh as well as the first transition for most house patterns and your style. If the X3 is too strong for the fresh, definitely bring the ball to a 2000 grit surface and then use Storm reacta shine to give you a more traditional skid/flip reaction. I would use your favorite ball drilling for the best results! Adam Chase Storm Staff

    RST X-3

    The X-3 is the newest HP4 ball in Roto Grips line. This ball is a hybrid coverstock similar to the RST X-1 that was released a couple of years ago. This ball gives me good length along with a quick response off of friction. This ball is going to be a great step down from a Roto Grip Gem and a great step up from something like an RST X-2. Throwing this ball on a house shot what I found is that this ball would be somewhat clean through the fronts and gives a quick jump off the friction. This is going to be a ball that you will be able to get left and throw it at the spot. Compared to the Reality Check I found this ball to be a couple boards more but not as round as the Check. I did also polish this ball and gave me a better look on what I was throwing on. The polish allowed it to be about 2 feet longer and gave a more continuous shape. This is going to be a good ball for speed dominate players and also for people who like to hook the lane. Alex Thomes #StormNation #StrikingWorldwide #SquadRG #Driven2Bowl
