A long time ago in a bowling center far, far away, the battle against ever-changing lane conditions raged on. As the lanes evolved—some with slicker surfaces, others with increased friction—bowlers sought the perfect weapon to combat heavier and longer oil patterns. Enter the Roto Grip RST Hyperdrive, the latest evolution in high-performance asymmetric power. At the core of this galactic powerhouse lies the RST (Roto Star Tour) asymmetric block, now enhanced with A.I. Core Technology. This combination delivers an unprecedented level of torque, energy transfer, and down-lane motion, ensuring maximum hitting power where bowlers need it most. The RST Hyperdrive generates superior mid-lane traction while maintaining a strong, continuous motion through the pins—making it the perfect solution for high-volume oil conditions. Encasing this advanced core is MicroTrax Solid, Roto Grip’s grippiest and most aggressive solid coverstock. Infused with a high concentration of nanoparticles, this coverstock displaces and absorbs oil efficiently, providing an ultra-consistent reaction even on the slickest conditions. Whether you're facing the challenge of fresh heavy oil or long-distance patterns, the RST Hyperdrive is built to cut through it all with ease. If you're searching for the ultimate high-performance asymmetrical ball that delivers the perfect blend of traction, control, and backend motion, look no further. The RST Hyperdrive is here to restore balance to your game, shot after shot.

The new ball in the Roto Grip HP4 line is the RST Hyperdrive.  The design team at SPI took the original core from RST-1 (RST (Roto Star Tour) + A.I. Core and wrapped it with very successful Gem Coverstock(MicroTrax Solid Reactive)  I drilled my 4 3/4 x 4 x 4 1/2 pin down.  I have been drilling the bigger asymmetrical pin down with my slower ball speed to help get them down the lane easier.  I am very impressed with how much continuation that I have with RST.  On the standard house shot I was able to open the lane up.  The RST handled the puddle with ease and still enough energy to get the ten out.  When hitting the dry a little early the RST just went into a roll and didn't over hook down lane.  With the great colors and great roll the RST is very easy to spot going down the lane. For a solid cover this RST hooks pretty good off the friction, still considered a slow response ball but still give good forgiveness.  Overall its the strongest over all ball in the lineup.  But I actually have the Attention star S2 a little earlier and less down lane. The RST is great addition to anyone's arsenal.

The Roto Grip RST Hyper Drive is a powerhouse for bowlers seeking strong mid-lane read with a controlled yet aggressive backend motion. Featuring the RST + A.I. Core and the MicroTrax Solid Coverstock, this ball blends the best of both worlds—strong traction in oil while retaining energy for a dynamic finish. Out of the box at 2000-grit Abralon, it handles medium to heavy oil conditions exceptionally well, providing a smooth yet continuous motion without being overly sharp. Compared to the original RST X-1 and X-2, the Hyper Drive offers a slightly earlier roll with a more predictable backend, making it ideal for players who want consistency without sacrificing hitting power. Whether you're a high-rev player looking for control or a straighter player needing extra motion, the RST Hyper Drive delivers a well-balanced reaction that excels in transition.
