BEHIND THE DESIGN:

Given the overwhelming success of the original GEMTM by bowlers of all skill levels around the globe, we felt it was important to make the next installment in this series something uniquely special like the first one. Lets just say it didn't take long for us to figure out that MicroTraxTM Pearl was the key element to this beauty.

So we went to work dialing in the proper ratios for each of the chemical elements to compliment the nanoparticles blended throughout the entire coverstock. This was the most crucial factor in making sure this pearl ball would conquer those Medium/Heavy Oil conditions.

Bottom line, the EXOTIC GEM will produce skid through the front of the lane while still digging into the midlane where the Defiant LRG will take over and produce the strongest continuation of any high-end asymmetric pearl ball on the market today!

    MAGIC

    Posted by Gil Barkman on Dec 28th 2023

    Magic Gem . Roto Grip Magic Gem Coverstock: 2000 Grit MicroTrax™ Hybrid Reactive Weight Block: Defiant™ LRG Core (Asymmetrical) Color: Citrine/Rhodonite/Jet Review: Don’t sleep on how good that Defiant core is. The origina Gem was a hook monster sometimes alittle too much and this is where the Magic Gem comes in. This ball is great on Heavy oil. Reads aggressively but does not really tilt hard which is good for those heavier condition. Reads the lane a little later than the original and where the original might slow up this continues to go. This ball is a keeper in my bag because I feel I can use this on anything out there. This ball is super versatile.

    About Me 900 Global Staff Left Handed: High Rev High Speed Player Pap: - 47/8 +1 Rev Rate: +-500 Speed 17-18mph Layout: 5 X 4 ½ X 2 Ball Video: https://youtu.be/t4ulgOF6n-U BIIIIIIIGGGGGGG Hybrid. The Magic Gem is the biggest hybrid that I have thrown but don't mistake that this is going to be too much because it isn't. The Magic Gem is a ball you are going to bring out when you are starting the transition from your stronger equipment. I think this will be a great transition killer ball. What I love about this ball is that you are going to be able to get a true read when the lanes become too dry for this ball. Unlike most bigger balls they like to quit on dry or puke out, but this does not. If you get it out to dry it still likes to come back. I think that if you have all three Gems you are going to have a pretty good 1-2-3 line up. Go out and talk to your pro shop person and see how this will fit into your line up.

    Exotic Gem

    Posted by Mancstorm on May 30th 2023

    A bowling ball can't hook early and snap in the backend but this ball comes pretty close to doing it!!!! Amazing the overall strength of this ball while still having an almost snappy backend reaction. High speed high rev players this ball is an absolute must!

    Roto Grip Exotic Gem

    Posted by Brian Watson on May 30th 2023

    The new ball in the Roto Grip HP4 line is the Exotic Gem. I am a big fan of the original Gem. So I was pretty excited to see a pearl version. I drilled mine very similar to the Gem, 4.5 x 5 x 2 basically pin above bridge drilling. The Exotic has great colors and is vert noticeable when going down the lane. With the same core as the Gem the Exotic still needs some oil up front. But the Exotic does have a pretty strong midlane and backend motion compared to the original. The exotic has been a little conditional to me with my ball roll. But I have had good success on the longer sport patterns. It's a different motion but when your lined up with it, strikes for days. Very strong Asymmetrical Pearl. Great addition to the RG line! Brian Watson Storm Pro Shop Staff PAP - 3 7/8 up 1 1/8 RPM - 400 MPH - 16-17 Tilt - 17

    Exotic Gem!

    Posted by Double B Ball and Drill on May 12th 2023

    The Exotic Gem is a House Shot Killer for me. Our house shot typically has quite a large puddle in the middle of the lane and quite a bit of dry to the right. I drilled my exotic pin down with a 3.5 x 5 x 3.25. And this layout for me allows me to play the track area a little longer but still gives me a decent amount of midlane hook. I am a higher speed higher rev rate player so on house shot I like to play as far right for as long as I can and the Exotic allows me to do that perfectly. It is also a great combo with the original Gem and Infinite Physix. If the lanes are a little more puddled up that the Original Gem come out first and then the Exotic. But if they start out a little more crispy down lane then I just start right off the with Exotic and then go to the Infinite if I get forced too far to the left. The Exotic for me does have its limits when I move left but it doesn’t have trouble until I start to encroach 5th arrow but that is the Infinites bread and butter for me. The Exotic is honestly one of the best balls I’ve ever thrown and if you need something a little stronger then this would be my #1 choice for you!

    Exotic Gem

    Posted by Casey Mattingly on May 9th 2023

    Talk about a killer combo…Defiant LRG Core which is the fastest revving asymmetrical core RotoGrip makes PLUS MicroTrax Pearl Coverstock, the earliest and most aggressive pearl cover RotoGrip offers (on any ball currently) is just a SICK combo! Also, when you walk into the pro shop this ball just jumps off the shelf! With as different of a motion as the GEM is, this ball is a great compliment. I really feel like after you can’t get any further left with the gem, the Exotic is right there to keep chasing it left. Even though its a fast revving ball, the thing keeps booming down lane This ball is unique in motion in my bag. It’s more of a tournament ball for me, I like to use it on more modified/sport patterns. Layout is 5.25X4x2 Balls getting a lot of play Infinite Physix: 5x4x2 HyRoad: 4.5x4.25x3.75 IQ Ruby: 5x4x2 Phaze4: 5x4x2 Fate: 5x4x2

    Roto Grip Exotic Gem Ball Review

    Posted by Pete Dohan on May 4th 2023

    Bowler Stats: Speed: 15.5 MPH Rev Rate: 300 RPM Tilt: 3-5 degrees Axis Rotation: 60 degrees PAP: 5 ⅜ over 1 ¼ up Layout: 5 X 4 X 2 ¾ VLS Video Ball Review: https://youtu.be/1uyCWBhckGE The Exotic Gem is the pearl version in the Gem series and features the Defiant LRG Core with a strong MicroTrax Pearl Cover. With how quick the X series is for me I decided to change my VLS layout a little to slow the ball down off the end of the pattern. This ball gives me the same length as all my other asymmetrical pieces in my arsenal like the X-3 and Infinite Physix but with this stronger pearl cover is slightly slower response off the dry than the X-3 and X-2 and not as continuous as the Infinite Physix. I have been using this ball a lot on the area house shots when I have fresher conditions. As the lanes transition and the oil in the heads thins out the stronger core and pearl cover does not get down the lane far enough and becomes too slow off the dry. This ball will definitely be in the arsenal this summer for the PBA 50 National Tour where we bowl on more volume. This is a piece I can see using on the 39’ Mike Aulby pattern.

    Perfect Stepdown!

    Posted by Zack Newman on Apr 11th 2023

    The Exotic Gem is almost exactly what I expected out of a pearl version of the Gem, however one surprising takeaway is the sheer midlane strength this core continues to provide, even with the shiny pearl cover. I drilled mine with a 5x4x4 layout for control through the front and a little smoother transition down the lane. I am a low track player, 470RPM, 14 degrees of tilt and 55 degrees of axis rotation, avg 16.4 MPH. It's a perfect combo along with the original Gem! I'm not able to stay right on top of where I begin when I transition out of the Gem (or Reality), but a nice 3/2 or 4/3 move inside gets me exactly where I need to be to continue striking on most conditions. I did adjust the surface to 500/1000/Step 2 polish just based on personal preference as I think I get a little truer read with a bit more teeth under the surface along with the extra traction the compound provides me.

    Roto Grip Exotic Gem review

    Posted by Mike Craig on Mar 31st 2023

    I drilled my Exotic Gem 5 x 3 x 2. I left this one at the box finish to see what it could do but then hit it with a 2000 pad to smooth it out. The early scuttle on this one from other staffers is strong motion. When I hear that I immediately think of putting more surface on it and throwing it when I am getting a flaky reaction on slick patterns with solid covers. I compared it to the INFINITE PHYSIX, GEM, and ABSOLUTE. Compared to the INFINITE, the EXOTIC is a stronger motion down the lane. INFINITE gives me more control, EXOTIC gives more forgiveness if I give the pocket away more. Compared to the original GEM, it is obvious a mismatch as the original GEM is just too much cover/core. It was a nice ball down when I surfaced it and needed to get left and the original GEM was sputtering. The ABSOLUTE was closer especially when both had surface on them. The EXOTIC was sharper down lane while the ABSOLUTE got more length. These two when surfaced the same can play off one another quite well. Drill up a EXOTIC GEM if you want a good house shot killer. It also makes a great compliment to the ABSOLUTE.

    Exotic GEM by Roto Grip Rick

    Posted by Rick Mitchell on Mar 31st 2023

    Roto Grip Exotic Gem – Defiant LRG core with e-Trax Pearl reactive cover stock – with Reacta Gloss finish. My specs: Ball speed 15+, Rev rate 425, PAP 4 and up 13/16 Layout: 50 x 2 x 60 used on SPL and HPL lane surfaces with Typical house pattern – both with a BIG cliff on the end of the pattern. Was quite excited when Schlem at Roto Grip decided to bring back one of the best asymmetrical cores back the Defiant LRG core, which means to me the fastest, captivating and STRIKING core Roto Grip has had, then they even made the ball sweeter, by wrapping that alluring cores with the most aggressive pearl cover to date, the e-Trax pearl. To put it in very simple terms for me, the ball was simply a “GEM” in both centers. The Exotic Gem with the strong combination of this cover and core, gives you the angular reaction in backend like a normal pearl, but you don’t have to “wait” to see the motion, and the direction the Exotic GEM goes through the pins is still strong, even though the ball starts up a little sooner, the ball does not QUIT. The Exotic GEM on the HPL lanes was a little bit strong on fresh, but with just changing a little bit in my set up and just use more of the middle part of the pattern, the ball struck A LOT. As the carry down starter, I did not have to change balls like I would normally do to stay inside of the other lefties I was bowling with, I was able to move my eyes down lane and close the angles up a little, and the Exotic GEM did not fail me. The center with SPL, it was the only ball I needed all throughout practice and scoring. By changing my release a little, I can manipulate the weight block to stand of a little bit earlier, to help with getting for end over end roll, which creates more energy down lane and still blow the racks apart. Don’t be afraid to invest in a Exotic GEM, even though it is an asymmetrical ball, it can be the best ball in your bag. Now for longevity of the Reacta Gloss on the Roto Grip demo balls, I usually have to touch up the surfaces with polish after they are used for a few events. I have not touched up the demo balls other than cleaning them with Reacta Foam to get the condition and grime off of the balls. The cover bonds very well with the new Storm Reacta Gloss “polish”. So, maintenance is very light over the course of its life. Thanks to the crew at Bowlers' Supply, Inc, Roto Grip, Colony Park Lanes and Vise Inserts for all the support and assistance!
