Roto Grip Duo

The Roto Grip Duo bowling ball utilizes a dynamically powerful core. This Mentor core was designed to generate midlane motion and produce a good measure of recovery at the backend. This upper-mid-performance ball uses the famous MicroTrax Pearl Reactive coverstock that stores energy through the front of the lane and unleashes that energy on the pins where it is needed. This ball not only has a dynamic look but also displays a dynamic motion on medium to medium/heavy oil conditions.

Question:


How does the Duo compare to the Hype pearl Thanks

9/8/2023 - By

Have an answer to this question?

Answer:


The Duo will have a stronger hook potential and this also helps it to work in medium oil and even some heavier oil while the Hyped Pearl works more in light to medium oil. They both have a pearl coverstock so they have similar length with the Duo reading just slightly earlier but still much stronger on the backend.
