    Additional product information:

    CORE TECHNOLOGY: The Rondure™ TOUR-X Core is a precision-engineered modification of the proven Rondure shape. By manipulating the internal mass densities, we have successfully lowered both the Radius of Gyration and the Differential. This intentional shift provides a highly controllable, medium-flaring asymmetric dynamic, perfectly tuned to deliver the smooth, professional-grade motion demanded by elite players.

    COVER TECHNOLOGY: The V-R1™ Hybrid Reactive is an advanced, nano-free formulation designed for a more aggressive footprint on the lane. By utilizing a precisely engineered 2:1 ratio—blending two parts solid & one part pearl—this coverstock achieves a potent balance of unadulterated havoc and refined predictability. The solid components ensure maximum mid-lane traction, while the pearl additive provides more response through the backend. The result is a tour-level coverstock that offers consistent & continuous motion.

    PERFORMANCE SYNOPSIS: Engineered specifically for bowlers seeking more overall control and a predictable, continuous motion throughout the entire lane. The combination of the Rondure™ TOUR-X Core and the balanced V-R1™ Hybrid Coverstock creates a highly versatile and tunable ball that excels on a wide variety of oil patterns, making it a staple for any competitive arsenal.

Additional product information:

Sometimes it's just better to let the R&D Team play around with various core and cover combinations and let them see what kind of chaos and havoc they can create. Such was the case with our latest addition to the HP3 Line known as the GREMLIN.

For starters, the R&D creatures found that when they "maxed out" the densities of both the block and the slug, the RG Value and DIFF Value both increased, while the mild asymmetric split lowered just a little, thus creating a cleaner and more angular motion down lane than we had ever seen before from this shape.

And of course they couldn't stop there. They then decided that in order to create a truly mischievous motion, they needed to develop a cleaner, more Versatile and more Responsive pearlized coverstock material, better known as V-R1™ (Versatile-Response - 1st version) to provide a new level of skid and snap that every bowling creature will come to appreciate.

Additional product information:

Since their conception back in 2016, the Hustle Series of bowling balls has provided outstanding performance above and beyond the retail price. From the 34th sanctioned 900 Series by the HustleTM INK, to countless TV appearances over the years on both the PBA & PWBA Tours. The various versions of the Hustle's have provided consistent reactions time and time again.

And while the inner Hustle Core has remained the same since day one, it's the different variations of the VTCTM (Versatile Traction Control) Coverstock - Solid, Pearl & Hybrid, that have kept this line viable on those Light to Medium Oil conditions for every level of bowler from the first-timers, all the way up to the pros.

    BEHIND THE DESIGN:

    Given success and popularity of the original RST™ Hyperdrive, we felt there was no better time than now to create a follow up that was the ideal complement to the Roto Grip lineup of balls. In order to make sure we got the ideal cover, we put the R&D Team and ball testers to work. 

    After multiple rounds of testing featuring both hybrid and pearl materials, it was a unanimous decision that we roll with and introduce our newest formulation of pearlized material better known as U-R1™ (ULTRA-Response version 1). Compared to previous nano-free pearl materials, this material provides plenty of push through the front of the lane from every angle, while providing ULTRA response to friction down lane no matter the style of bowler. Lets just say if you thought the original Attention Star was out of this world... WAIT UNTIL YOU SEE THIS!

     Key Features:

    • The RST Hyperdrive Pearl is a pearl asymmetric option that designed for medium to medium/heavy oil conditions.
    • The ball is finished with Power Edge™
    • Core: RST™ + A.I. Core – Same proven core that was used in the solid.
    • Coverstock: U-R1™ Pearl Reactive – NEW pearlized reactive coverstock. It’s nano-free that creates ULTRA response to friction down lane.
    • This combination of Core & Cover generates ease of push through the front of the lane, while providing a strong, responsive, and continuous move at the breakpoint making it ideal for all styles of bowler from a variety of angles on the lane.


    Plays Well When:

    • RST™ Hyperdrive – is too early and something cleaner with more reaction down lane is needed.
    • Attention™ Star S2 – is too early and something cleaner with more reaction down lane is needed. Attention™ Star – isn’t quite enough down lane or through the pins.
    • Gremlin™ - isn’t quite strong enough and a stronger core and cover combo is needed.
    • Rockstar™ - is too early and something cleaner with more reaction down lane is needed.
