The X-1 is the newest addition to the HP4 line. It features the MicroTrax Hybrid coverstock. This ball doesn't do anything flashy; it simply gets the job done. In the past, Roto Grip has been known to make some of the best Asymmetrical balls in the industry. The X-1 proudly carries that torch. I found the X-1 to be similar in overall strength compared to the UFO and the X-1 is about a zone stronger than the Nuclear Cell. The UFO and X-1 differ because they read the lane at different points. The UFO will be slightly earlier because of the Solid MicroTrax cover whereas the X-1 will be slightly cleaner and retain more shape downlane because it has the Hybrid Cover. In all, you'll be able to throw the X-1 on heavy conditions when you need slightly more length than the UFO is giving you.

This ball is SICK!  I am so happy with this release! This ball is super versatile.  Whatever I do with my hand, this ball responds to.  I can get right and get up the back of it or I can get in and get around it and it will boom down lane.  My first 6 games with this ball was 804 and 802.
247, 257, 300, 289, 256, 257.

Along with the versatility there is also its hitting power.  This ball goes through the pins SO well, destroying racks.

The only downfall of this ball is the color.  I personally like the darker colored balls, but some may think that this ball doesnít have the shelf appeal as the other Asymetrical ball with the same release date, Proton Physix.

Pick yours up on Black Friday!!

What condition were you bowling on, to put up such lofty scores?
Some days you're the bug....some days you're the windshield...that's bowling!

The RST X-1 features the nano based MicroTrax hybrid cover formula and new dynamic and high torque asymmetric RST or Roto Star Tour core.  MicroTrax is very similar to Stormís NRG coverstock, though is a little stronger to my knowledge, and the 3000 grit hybrid version instantly reminds me of the PhysiX.  The RST core comes in at a 2.53 RG which is medium and fairly high for an asymmetric ball, an .053 differential and an .016 split or intermediate differential.  The medium RG is going to help the ball scoot through the fronts a little easier while the diff and split create plenty of torque and motion down lane.  The overall package reads like a slightly smoother PhysiX or more usable Halo Vision to me, all of which is good news.  The PhysiX could offer a little too much boom down lane sometimes and the Vision was strong enough to take it out of play on all but the heaviest of conditions, while the RST still provides plenty of hook to tackle heavier stuff but also play more comfortably than I expected on a house shot.  With 1 being the lowest and 10 being the highest, I rate the RST a 9 for hook, a 5 for length, and a 5 for backend strength.

When I first saw this ball was going to be released, I knew it was going to be an instant winner for me.  I really love the Storm Physix and knew this RST-X1 would be a great compliment to it.  The RST-X1 brings the all new Roto Star Tour with the MicroTrax Hybrid Coverstock.  This combination is not only predictable but allows for great continuation to be used on a wide variety of oil patterns.  This ball reminds me of an asymmetrical IQ Tour. It is a ball that most people will love because of its roll versatility and drilling versatility.  This ball also handles surface changes well and don't be afraid to polish this one either.  A cleaner and faster response will allow for better use on drier lanes and older lane surfaces.  For those who only drill 1 or 2 balls a year, this is a sure winner to be one of those balls.  This ball would be a great piece for any arsenal from the average league bowlers to the competitive tournament bowlers.

Roto Grip's RST X-1 brings a brand-new Roto Star Tour core design plus an updated and familiar cover... and results in what might be the surprise of 2020 for me. The 3000-grit MicroTrax Hybrid coverstock is not at all hurting for traction, but that new medium-RG asymmetric core provides a ton of midlane punch while also continuing downlane and through the pins better than any other asym core that I've ever thrown. I find it hard to put this ball down... and I'm guessing you will too!
