The Roto Grip Magic GEM: a captivating and powerful bowling ball. Roto Grip combined the MicroTrax Solid and MicroTrax Pearl components to create the MicroTrax Hybrid Coverstock, resulting in an exceptional hybrid high-performance ball. The Defiant LRG Core, originally featured in the GEM, adds remarkable style and performance to bowlers of all skill levels. Its unique density composition makes it the fastest-revving, strongest-continuing, and lowest RG asymmetrical core in Roto Grip's current lineup. This coverstock technology excels in performance, boasting a 100% nanoparticle load for midlane traction and friction response. It maintains its surface profile longer, ensuring maximum performance. Plus, it excels at displacing oil, providing forgiveness for less-than-perfect shots. Designed for medium-heavy to heavy oil conditions, the Magic GEM is a valuable addition to this series of balls, complementing the GEM and Exotic GEM without overlap.

The newest addition to the Gem family is going to be a great addition. One of the biggest issues that I saw with the Gem was that it was so early and strong that you would lose carry from time to time. The all new Magic Gem has solved this issue in a major way! The Magic Gem is still early and strong, but its biggest attribute is that it is a touch more angular. The angle that this ball creates compared to the OG Gem can be the difference between striking and leaving a flat 10 or weak a 7 pin. The Magic Gem features the same Defiant LRG Core, however, its has the MicroTrax hybrid coverstock compared to the Solid coverstock in the original Gem. I am very pleased with what I have seen from this ball so far and I am sure this ball will get a ton of use from a variety of bowlers, do not hesitate, go out and get yours today.

The New HP4 release from Roto Grip is the Magic Gem. The Gem line has been at the  top of the strength charts since they hit the market and the Magic Gem certainly continues that trend. The Defiant LRG core is this time wrapped in a sanded Hybrid version of micro-trax. While the 2k finish gives it some mid-lane teeth the 2part pearl 1 part solid make-up makes this ball continuous.

This has been the most usuable of the Gem releases for me personally. Where I felt the first two were pretty conditional for me because of my ball speed, the Magic Gem is very continous. It doesn't lock up and get forward the way the other two did for me so I don't have to have the giant puddle to push it down-lane or the mega hook backends to get it to tip up.

I tested the Magic Gem first time out on our house pattern. While the length and Volume of our pattern can make the lanes very tight, the high friction surface in the front of the lane can make the strongest balls tough to use. Magic Gem's reaction seems to give you the best of both worlds, it sees the mid-lane without over-seeing the fronts and it continues through the back-end. I was very impressed with this ball on the fresh as it was great at blending out the lane. It reacted well through the transition and until the lane really burnt up the last game it gave me a predictable motion as I went left.

The versatility of the Magic Gem makes it useful for more people. It's strong enough for the rev-challenged and speed dominant players but continuous enough for the people who struggle stay in a ball once the lanes start to transition. I would recommend this ball for pretty much any style of player as a first ball out of the bag.

Magic Gem:
The Magic Gem is the strongest ball I currently have in my bag. We see plenty of overall motion with this ball as it reads the kids very strong and continues very well. This ball is designed for those heavier oil conditions or when they're absolutely walled and you need the ball to get ramped up early to fight those tighter conditions.
I see myself using this ball more on sport conditions versus house as I typically need a cleaner reaction on house to blend out the pattern more which provides additional miss room. For those who liked the X3 from Roto Grip you will enjoy the Magic Gem.
TNT Infused:
The TNT Infused is an excellent benchmark symmetrical ball to throw when the fronts begin to hook early yet provides tons of mid lane read. The Infused will be more usable for most players against the original TNT as it provides much more back end reaction and doesn't see the fronts as early as the original.
I have found success using the TNT as a step down off my stronger balls like the Magic Gem, Eternity PI and Xponent. I am a big fan of this ball as it provides plenty of usability when I need to  open my angles up on those medium to higher volume patterns. The Infused will be good on varying patterns from house to sport.

Bowler Specs:

Review:
The Magic Gem is a very aggressive Hybrid at box finish. The Magic Gem is more continuous down lane than the Original Gem due to the fact it is a hybrid so it stores more energy and does not go forward to soon. I do feel the Magic Gem will perform better on a house shot with a smoother, polished surface than box. This ball will need some oil especially up front to roll at its best. I feel that weaker layouts would work best unless a bowler really needs help creating motion because the Magic Gem has a very powerful hook potential out of the box. I have not rolled this ball a lot but I am able to carry lighter off hits with it and solid hits destroy the rack. So far I have only tested the ball at box finish. This ball will be great for the flatter tournament shots or for higher speed or lower rev bowlers. Roto Grip has done an excellent job of placing this ball right between the Original Gem and the Exotic Gem. I am looking forward to getting this ball on some wetter lane conditions to see what it can do. The Magic at box is too strong for the house shots in my area.

Summary:
The Magic Gem sits right between the Exotic and original Gem in motion.
The Balls colors look great as it rolls.
If you are looking for a strong Hybrid give the Magic Gem a look.

Review:
The Magic Gem features the MicroTrax Hybrid Reactive coverstock which makes the Magic Gem distinctive in the Roto Grip and SPI line of bowling balls. The original Gem is noted as the earliest rolling ball at the current time. The two part pearl one part solid makes up the Magic Gem.

Although the Magic Gem will provide the bowler extra length, you can expect the Magic Gem to also give you more reaction when the ball encounters friction compared to the Gem. Anything you desire in a ball to create hook, more hook, oh and can you say "hook!". This one is for you. You should expect an early continuous, strong reaction.  The best part is the Magic Gem will provide continuous lane motion early on, yet provide great control.

The Magic Gem achieves some length so the ball does not "hook at your feet" which would have occurred with older generation of bowling balls. The Magic Gem will work best on long, medium and higher volume patterns.  If your desire is to stay left before and as the the lanes transition this ball will not disappoint. If you want the biggest, aggressive and most powerful hybrid on the market today in your bag, this is the one!  Don't hesitate to try out the Roto Grip Magic Gem today.

The Roto Grip Magic Gem is the newest HP4 ball to hit the SPI line. The Magic Gem features the MicroTrax hybrid cover that’s wrapped in the same Defiant LRG core that was featured in the GEM and Exotic before. The Magic Gem for me is the perfect step down from the original when I need slightly less traction and more overall shape. The Magic Gem is the perfect compliment to the Reality, being slightly cleaner and faster.

Roto Grip Magic Gem
Coverstock: MicroTrax Hybrid Reactive
Finish: 2000-grit Abralon
Core: Defiant LRG Core
RG: 2.47, Diff: 0.053, PSA: 0.016 (15 lb.)
VLS Layout: 5 x 5 x 2
Dual Angle Layout: 65 x 5 x 30
PAP: 5 3/16” right x 5/8” up
Rev rate: 400 rpm
Average speed: 16.5 mph
Location: Prairie Lanes, Sun Prairie WI
Pattern: Medium volume THS

The Roto Grip Magic Gem is the newest addition to the Gem series, this time featuring the hybrid MicroTrax cover that’s 2-parts pearl and 1-part solid and wrapped around the ever-familiar Defiant LRG core.  The intent with this release was to compliment the reactions of the original Gem and Exotic Gem by slotting between those two balls – a little cleaner through the fronts than the Gem but with more midlane read than the Exotic Gem.

After my first few shots, it was clearly evident that the Magic Gem is a very aggressive ball that is more continuous downlane than the Gem, and thanks to the 2000-grit Abralon hybrid cover it picks up and reads the body of the oil pattern better than the Exotic.  I threw the Magic Gem after the Saturday morning junior league, and even though there was a fair amount of carry down from the kiddos, I was still forced to move further left than expected to find enough oil to get the ball down the lane.  To my eye, the Magic Gem creates a strong and powerful reaction that’s more reminiscent of the Gem, but the Magic manages to be a bit cleaner and creates more downlane motion that better drives through the pins.  The Exotic Gem or Clone would be a good option to ball down to when the Magic Gem becomes too strong.

I expect the Magic Gem to be a great ball for blending out the over/under reaction you typically see on league house patterns.  It’s super strong out of the box, but I suspect it will become more versatile as it lane-shines after a few games or by adjusting the surface with a 3000- or 4000-grit Abralon pad so that it doesn’t dig so hard into the oil.  I see the Magic Gem as being my go-to for heavier volume patterns when I need a bit more shape than what the OG Gem is capable of.  If you’re looking for a ball with a powerful and aggressive reaction, there’s no need to look further than Magic Gem.

Roto Grip Magic Gem – WWRD 10/20/23 Cover: MicroTrax Hybrid Reactive Core: Defiant LRG RG: 2.47 RG. Diff.: 0.053 Finish: 2000-Grit Abralon Roto Grip’s new Magic Gem is a Hybrid (2/3 Pearl, 1/3 Solid) Asymmetrical piece that is good for Medium-Heavy Volume Patterns. PAP is 5 5/16 R 1 3/16 Up. Rev Rate: 400. Speed: 16.5. Drilled this piece with the Pin above the bridge, CG kicked out 1” from the palm, and the Mass Bias 1/2” to the Right of the Thumb. I threw this piece on a fresh 48’ Shark pattern. Out of Box ball motion started in the mids with smooth Continuous Motion on the backend. Once the pattern broke down, I moved 5-5 Left. It read in the mids with continuous backend. I compared this piece to the Roto Grip Clone and Tour Dynam-X. Clone was 1-1 right and the Tour Dynam-X was 2-2 Right of the Magic Gem. This is a good starting piece on the fresh oil. This ball will be good for all types of bowlers.

Roto Grip Magic Gem
Coverstock: 2000 Grit MicroTraxâ„¢ Hybrid Reactive
Weight Block: Defiantâ„¢ LRG Core (Asymmetrical)
Color: Citrine/Rhodonite/Jet

Review:
The Gem series has been a home run for that first out of bag bowling ball and not to mention the awesome shelf appeal! If you love those bowling balls that like to move this will not disappoint. Our style: tweener, 350-375 revs, 16.5mph, layout of choice is 4x4x2 (pin is above bridge). We really like this ball for fresh tournament and house patterns. We often find ourselves beginning with this piece in game 1 and transitioning to something a little smoother down lane in the later part of game 2 and game 3. This ball may not be as versatile as some of the other SPI asym bowling balls but it must not be overlooked for its power on the fresh. It really is a true Gem. This may be more of a niche piece but it is definitely worth checking out at a local matchmaker to see if it fills that Magic gap in your arsenal!

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!

The third release in the Gem line combines the best of the two previous releases.  The Magic Gem has the same Defiant Asymmetric cover as the others, but the Magic is wrapped in MicroTrax Hybrid Reactive coverstock finished at 2000 grit abralon.  The 15-pound version has a RG of 2.47, a differential of .053, and an intermediate diff of .016.  Drilled at 5x4x2 (pin above bridge for me), this ball is a monster.  It has almost as much total hook as the original Gem, but the motion is very different.  The Magic Gem’s reaction is more delayed than the original.  It pushes a good 3-4 feet further down the lane before it starts to read the lane.  The backend motion is much stronger than the original Gem.  This ball is the perfect complement to the original Gem.  Once the original is starting to burn up a little too soon, that is the time to go to the Magic Gem.  The Magic needs a good amount of oil to be effective, but there is very little quit on the backend even when your angles are pretty open.  In my opinion, the Magic is the most versatile of the three Gems.

Orientation:  Right Handed
Rev Rate:  400 RPM
Speed:  16-17 MPH
PAP:  4 ½ over and ½ up

Location:  Enterprise Park Lanes, Springfield MO
Pattern:  High Volume THS
VLS Layout: 
Layout 1:  5 x 4 x 2 ½  (pin above bridge)
Layout 2:  4 ½ x 4 x 4 1/8 (pin below bridge)

The Magic Gem is the strongest Gem in the back part of the lane ever!  Think early jerk.  The Gem is early and slow.  The Exotic is cleaner and snappy.  The Magic Gem hybrid version is earlier than the Exotic by a good deal and WAY more on the backend than the OG Gem.  Honestly it was hard for me to keep it online unless I threw the ball pretty hard.  If you want to HOOK the ball I honestly can’t think of a ball that hooks more overall for me.  If you don’t have oil or ball speed, BEWARE!  This is a ton of HOOOOOK.

Roto Grip Magic Gem Ball Review by PJ Haggerty

The Magic Gem is the latest addition to the HP4 line at Roto Grip.  After the previous, extremely successful releases like the original and Exotic Gem, the Magic had big shoes to fill.  The Magic Gem is different than the previous releases because of its coverstock.  The original Gem provided a solid coverstock while the Exotic Gem provided a pearl coverstock.  Naturally, the Magic fits right in the middle providing a hybrid coverstock while using the same Defiant LRG core.

With an RG of 2.47, differential of .053, and PSA of .016, those numbers indicate a ball that wants to read the front part of the lane, dig hard in the mid-lane, and change direction at a moderate level into the pin deck.  The hybrid coverstock will create more length than the original Gem, but after throwing the Magic on several surfaces and conditions, I see the Magic wanting to dig similarly to the original Gem.

I’ve drilled one so far and think it rolls great.  It’s mapped out as 5.5 x 4 x 3.  This puts the pin in-between my bridge and middle finger and the CG is just to the right of my thumb.  I’ve had the most success with the Magic Gem when I’ve had to keep my angles tighter and when I need something to pick up, but not change direction super hard down lane.  I’ve found a ton of consistency with how it rolls and goes through the pins.  The Magic Gem can be extremely useful because I think it’s different enough compared to the other balls in the line that it makes complete sense to drill.

Roto Grip Magic Gem
Coverstock: 2000 Grit MicroTraxâ„¢ Hybrid Reactive
Weight Block: Defiantâ„¢ LRG Core (Asymmetrical)
Color: Citrine/Rhodonite/Jet
Review:
The GEM line has continued the success of one of Roto Grips greatest lines of all time in the Defiant series. The original Gem and the Exotic Gem have been great additions to the line and have continued the tradition of a strong asymmetric ball that will not be uncontrollable. The Magic Gem is another addition to that tradition. Out of box I felt this ball was just as strong as the original Gem, but the hybrid cover stock gave the ball more shape at the mid-lane rather than earlier or later on the lanes like the other iterations of the Gem did. Besides being a great overall ball, the shelf appeal has been able to makes sales on its own. This ball really pops when going down the lane and really is a unique ball when going down the lane.
