Roto Grip continues its successful Gem line with the release of the Magic Gem. And what makes the Magic Gem so magical? Roto Grip has wrapped the MicroTrax Hybrid Reactive coverstock around the proven Defiant LRG Core, making the Magic Gem a predictable pin-crushing rolling machine. So, let’s take a closer look at what makes the Magic Gem an excellent choice for your arsenal.
The LRG Core has been the heartbeat of Roto Grip’s Gem line and continues its pumping success inside the Magic Gem. Being a straighter low-rev player, I liked how the Defiant LRG had a smooth and continuous roll in the mid-lane yet stood up with authority when it turned off the pattern. And rather than being lazy and slow to make its decision like large asymmetrical cores tend to do, the Defiant LRG Core makes a decisive and predictable motion to the pocket and still retains a powerful punch through the pins. And being a large asymmetrical core, I could count on the Defiant LRG Core to have a strong and continuous roll through the pins without the deflection I tend to see because of my slower rev rate. So, if you are a down-and-in player like me, you can count on the Defiant LRG to kick out those troubled corner pins we tend to see and keep your game in play when you need it most.
The Hybrid MicroTrax Coverstock is an excellent choice for straighter, low-rev players like me. The two-part Pearl and one-part solid Hybrid mixture brings a combination of traction and smoothness that is ideal for players like me. Unlike some solid coverstocks that tend to roll out and lose energy through the pocket, the MicroTrax Hybrid has the right amount of solid to get you through the heads without being overly aggressive, which causes the ball to burn up energy. And unlike pearl coverstocks that go far too long before they make their turn, causing you to 2-8-10, the two-part Pearl in the MicroTrax Hybrid coverstock has smooth traction when it finds friction and blends the transition of wet/dry without being jumpy or erratic off the pattern. So, if you are a straighter, down–and–in bowler like me, you can count on the MicroTrax Hybrid Cover to deliver a predictable and stable motion all night.
In closing, the Magic Gem is an excellent new release by Roto Grip! And with the Defiant LRG Core and the MicroTrax Hybrid Coverstock combination, the Magic Gem is perfect for any down-and-in low-rev player like me. So, stop into your local Storm VIP Pro Shop and have the Roto Grip Magic Gem ready to roll for tonight’s league. Your game, scores, and team will be glad you did!
