How does the storm Physix compare to the Roto Grip RST x-1 Bowling Ball
My Rated series was designed to give you the ability to compare any ball vs any other ball, but I still receive a lot of questions about specific comparisons, so rather than making you dig around in the playlist, I’ve decided to combine several of the most popular or requested comparisons into single videos! If you have a comparison you want to see, put it in the comments and I’ll make it happen!
Storm Physix Bowling Ball Ratings For Hook, Length and Backend
The PhysiX features the NRG hybrid coverstock and asymmetric high torque Atomic core. NRG hybrid is a cover we rarely see stateside, but which also got featured on the Super Son!Q and All Road. NRG is smooth, strong, and continuous, but the Atomic core gives it decidedly more shape than we saw out of it on either the Super Son!Q or All Road, core numbers are a 2.48 RG, .053 differential, and .017 split or intermediate differential, and as you can see it’s quite dynamic. The PhysiX is powerful across the board, lots of traction, lots of backend, one of the highest combinations of both hook and backend that I’ve thrown, and it was very popular. I rate the PhysiX a 9 for hook, 5 for length, and a 6 for backend. Fortunately we have a handful of great replacement options. I have the new Roto Grip RST X-1 a tick smoother on the backend than the PhysiX, but several other people have remarked that it’s virtually a PhysiX for them, so that will be the closest, the Rubicon isn’t quite as strong, but the look on the lanes is very similar, and I’ve also added the Nuclear Cell as it’s also fairly close if you take it to 3000.

Roto Grip RST X-1 Bowling Ball Ratings For Hook, Length and Backend
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 Storm’s 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. It’s closest to the PhysiX on overall strength, the Rubicon on length, and the IQ Tour Nano Pearl in backend strength.

The development of the new PhysiX has been a sprawling process that has spanned several years. Dialing in the precise dynamics of a shape that is iconic to the Storm brand was our ambition, and the PhysiX became our destination. Yes, it officially boasts a 0.053 total differential in a 15 pound ball, and the rest of its prodigious oomph accepts credit from the strategically placed inlets surrounding the oval bolt and greater mass displacement along the z-axis creating an enhanced intermediate differential. With extreme amounts of power and dynamics, the PhysiX almost feels like cheating.

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.

RST – Roto Star Tour Core…
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 near the bottom of the void area not to affect the bottom mass of the core all that much. Thus, making this core a “Tour Level” type core design.
Behind the X-1 name…
When it all began back in the early 1950’s, Roto Star (later known as Roto Grip) quickly became known as the “High Performance Bowling Ball Specialists.”
Because of this industry leading mantra, and with the latest creation of the Roto Star Tour Core, it only made sense to go back in time to recapture the vibe and pay homage to those balls that set the standard for technology and development.
That is how the RST X-1 was born!
