Roto Grip's new HP4 release is a heavy-oil hooker called the RST Hyperdrive. The powerful Microtrax cover that was featured on the Gem is teamed up with Roto Star core that was featured on the previous RST releases, this time upgraded with the Amplified Inertia (A.I) technology. This combination should give you a stronger midlane read than the previous RST balls but more down-lane hook than the Gem.

I tested the RST Hyperdrive for the first time in league. Our house pattern is 44 feet long and high volume so this seemed like the perfect spot to throw it. The first few shots did want to pick up right away, which wasn't too surprising with how much our front panels hook. I bumped a little left to find the pocket, but the ball was pretty flat going through the pins. I had trouble getting the ball far enough right and when moved left enough to get it there, it didn't retain much energy.

The adjustment I've found that works best when I see this ball reaction is to throw the ball a little bit further out on the lane, to take the early friction out of play. This worked very well with the RST Hyperdrive as long as I got it into the friction to the right early enough. If I got the ball more in the track around 7-8 it had a chance to strike but it showed noticeably less energy going through the pins compared to if I got the ball out more in the 4-5 board range. If I made sure to catch the fingers well, I could strike pretty consistently in this range of boards down-lane.

I think this ball will be pretty popular for people who are a little more speed dominant or those bowling on heavier oil patterns. It does have a reasonable long transition when it starts to hook but that was also partly due to my choice of layout. In a house with quicker back-ends but the same oil up front I think it would look fantastic.It definitely falls in between a Gem and the RST in terms of reaction and shape.
