Luke Rosdahl Rated Rumble: Roto Grip Rubicon VS Storm Phaze 2 Bowling Ball

How does the roto grip rubicon compare to the Storm Phaze 2

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!

Roto Grip Rubicon Bowling Ball Ratings For Hook, Length and Backend

The Rubicon features the etrax s20 solid coverstock and the new mild asymmetric Rondure core.  Etrax is a cleaner and more responsive formula like R2S, but stronger overall.  The new Rondure core in 15 pounds has a 2.49 RG, .052 differential, and an .011 split, or intermediate differential.  The rg and diff are exactly the same as the Idols, and there’s somewhat of a shape difference, but especially when comparing it to the Idol Pro, which shares the same base cover formula, you can see extra traction and extra aggression down lane out of the Rubicon.  It’s very reminiscent of balls like the Code X and Alpha Crux, which were higher traction balls with a firm and predictable motion down lane, but still with a focus on control.  With 1 being the lowest and 10 being the highest, my hook rating is 8, my length rating is 5, and my backend strength rating is 6.  The Rubicon’s hook potential is closest to the Phaze 2, the length is closest to the RST X-1, and the backend is closest to the Axiom Pearl.  Select the next comparison you’d like to see from the links on the screen, or scroll down to the description to find links to other choices.

The Phaze 2 features the now goated combination of the TX-16 solid coverstock and the symmetric Velocity core.  TX-16 was only used once stateside, but is a chemically enhanced and very balanced cover.  It gets traction early without slowing down TOO early, and creates a consistent and predictable amount of shape.  The Velocity core comes in at a 2.48 RG and an .051 differential in 15 pounds and has become legendary as the Phaze 2 rose to become one of the premier sport condition balls in the entire industry, becoming a favorite of many of the pros and perhaps most notably for Kris Prather.  Velocity is quick revving, but at the same time very even and continuous, it just keeps winding and climbing.  The combination has created one of the most consistent and versatile balls in the industry and company history.  With 1 being the lowest and 10 being the highest, I rate the Phaze 2 an 8 in hook, a 5 in length, and a 4 in backend strength.  It’s closest to the Rubicon in hook, the IQ Tour Nano Pearl in length, and the Hustle PBR in backend strength.  Select the next comparison you’d like to see from the links on the screen, or scroll down to the description to find links to other choices.  Thanks for watching and may the strikes be with you.

A drastic departure from our traditional symmetrical core or symmetrical weightblock designs in the HP3 line, the asymmetrical Rondure™ Core was developed in increase overall ball motion throughout the lane without the aid of an added balance hole.
Featuring our most recent formulation of eTrax™ solid coverstock technology, this cover is easily sanded or easily polished in order to meet your needs on a variety of conditions without losing traction and responsiveness to friction.
Engineered for those Medium to Medium-Heavy Oil conditions, we felt it was an absolute must to provide added core technology in this line in order to create advanced ball motion since balance holes are no longer legal in sanctioned competition.

The new Phaze II features both innovative core and coverstock technology, proving again that Storm is the leader in bowling innovation. Advancements in the core shape are easily seen with the naked eye. This fast-revving shape, the aptly-named, supercharged Velocity? Core helps you crush pin after pin as it produces more ball motion than any other shape in our Master Line. It smooths out the backend reaction without over-reacting and avoids creating an undesirable last-second movement.

TX-16 (Traction-X 2016) is what emerges from countless hours in R&D to develop the finest coverstocks on the planet. This solid reactive blend leaves an incredible footprint on the lane. The marriage between the core and the cover produces the strongest motion of any symmetrical Storm ball to date.
