Passing the Torch | Roto Grip Tour Dynam-X vs Storm IQ Tour Solid!

Roto Grip Tour Dynam-X Bowling Ball

From day one, the end goal was to develop and create a high-performance ball from a completely different dynamic performance-focused perspective. Tour level players and above average bowlers from around the globe have always asked for a ball that produces control and continuation with minimal direction change in order to battle those tougher and more demanding and over reacting conditions. They spoke, we listened! So, we went to work to formulate and create the ultimate “TOUR PLAYER” ball.

And truth be told, after months and months of trials and errors, we were finally able to construct the optimum control and continuation for every style of bowler no matter their rev rate. Control, stability, and versatility unified into one dynamic ball that is a must for every single serious or semi-serious bowler.

Rondure Core

When a symmetrical core shape just isn’t enough or quite right, and a big asymmetrical core shape is just flat out too much, the answer is simple – the Mild-Asymmetric Rondure Tour Core. Why is this version considered a “Tour” model you ask? We thought you would never ask. From the original version of this shape previously introduced and used in the Rubicon™ Series, we changed the core values significantly to create a faster revving version that stays on-line easier and longer with less change of direction due to the Differential value being cut in half.

So, no matter how you throw this ball, whether you have a super high rev rate or a super low rev rate, or a rev rate somewhere in the middle, this Low RG, Low Differential, Mild Asymmetric Differential core produces a constant stable motion off your hand and all the way through the pin deck.

Since we built the IQ Tour Edition to be the foundation of your arsenal, you can be confident in the fact that this ball will be consistent across a variety of lane conditions.
