Additional product information:

Dating back to the mid-1950’s, there is a reason Roto Grip is often referred to as the “Original High-Performance Bowling Ball Specialists.”
Our latest asymmetrical creation continues that tradition with the development of the RST Core which produces consistent core torque and energy transfer down lane where it is needed most.
From there we formulated the most versatile MicroTrax Hybrid Coverstock to date which produces optimum responsiveness to both oil and friction.
It’s ok, you can thank us later!

    This ball is a monster! I shot 802 with it right out of the box. Some of you might want to shine it a bit depending on the oil volume you bowl on - I chose to let lane shine do it's job. I'll be buying another one and storing it for the day this ball is no longer available.

    Ball Specs: Roto Grip RST X-1 Cover: 3000 MicroTrax™ Hybrid Reactive Weight Block: RST™ Core (Asymmetrical) Color: Black/Dark Forest/Forest Pearl The first thing that caught my eye about this ball was the name. It really stands out as a unique name when it comes to a bowling ball name. Now on to the performance of the bowling ball. This has to be one of the best balls I’ve thrown recently. It does a great job of getting down the lane while maintaining energy for when it hits the pins. I’ve done a little surface experimenting with this ball and have managed to still keep the same result. I would consider this a step down from some of the other high end asymmetric bowling balls that Storm/Roto Grip/ 900 Global offer, but I still found a good place in my bag for this ball. Overall I see this ball great for both the house bowler and the tournament bowler a like. It’s versatility allows for a wide range of bowlers to enjoy this bowling ball and take their game to the next level. Will Tefft Roto Grip Staff Member #SquadRG

    The new RST-X1 is the newest HP4 ball introduced to the roto grip line. I'd put this ball in between the ufo and the rubicon. To me this ball for being a big asymmetric hybrid gets through the fronts reads the mids and had a lot of pop off the spot. It kind of reminds me of an Original Physix from storm. If you're looking for a dull asymmetrical bowling ball that is great left to right this is the ball for you! Go to your local pro shop and get one of these you won't be sorry!

    The ball is amazing! 2 league nights so far. 682 and 761. Lay out 35x5.25x40. Couldn't have asked for a better product. I would reccomend this ball to a lot of people.
