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!

    So clean and so strong

    Posted by Steven Collins on Feb 22nd 2023

    Likes: One of the cleanest and strongest Pearl balls since the Altered Reality. This ball gets down the lane and makes a left turn. Just as good as the original, great 1-2 punch on a THS or pattern. This ball will be in the bag for a long time. So good I might drill 2. Dislikes: None

    Exotic Gem

    Posted by Joel Donner on Feb 21st 2023

    Let’s Talk about the Exotic Gem. This ball is a monster to be honest. This is one of the strongest pearl balls that I have thrown. The first few times I threw it I liked it but wasn't in love with it until I figured out that I had to get deeper than I was. I was trying to play to straight in the beginning until I figured out that the Exotic Gem definitely likes oil. As soon as I moved deep enough, I was able to open the lane up quite a bit and was able to create some area. The Exotic will allow you to start deeper from the beginning and allow you to stay away from mid set traffic on the track area. This will fit nicely in my bag for when we have a few more lefties on the pair or in a tournament so I can start and stay deep and not have to move or make so many ball changes. The Exotic Gem is a weapon that will be firmly planted in my arsenal, and it hits like a tank. Very powerful ball and looking forward to throwing the Exotic more.

    Exotic Gem is HUGE!

    Posted by Chris Martinez on Feb 20th 2023

    Bowlers Info: RH tweener, PAP 4-5/8 x 3/4 up, 380 RPM, 13* of Axis tilt, 60* of Axis Rotation Ball Layout: 45 x 5.25 x 35 VLS: 5-1/4 x 4 x 2 Finish: OOB The Exotic Gem has quickly become one of my favorite pieces in league. I drilled mine 5-1/4” pin with a 2” pin buffer which put the pin high above my bridge. What I didn’t anticipate is how much this thing HOOKS!!! For me, this is cleaner but much bigger than my Infinite Physix. When this piece hits friction, it turns over pretty hard and simply throws pins everywhere! It’s not quick off the spot, a bit slower to transition, but once it changes motion, watch out! This hooks pretty well in oil as well and have used this as a transition piece after my Phaze 2 starts to burn up and I want to move things inside a bit. If your looking for hook, you’ve found it in this one for sure! Chris Martinez Storm Amateur Staff www.stormbowling.com

    Beautiful going down the lane hitting twice as hard

    Posted by Tarik Joyner on Feb 8th 2023

    I drilled this one 45x5x45 this is my standard pin layout for a asymmetrical ball. This ball wowed me from the start!! Makes such a great combo with the original Gem. I’ve used this both on our regular house shot as well as on a longer sport pattern 44ft. On a house shot this ball will be very good for those bowlers that don’t throw the ball very hard, or have a lower rev rate but still want that pop off the back end or to kick the 10 pin out the pearl cover stock clears the fronts very very easy playing up the right side can be a no no when those outsides dry out one thing about this ball is when it sees friction its gonna take a that left hand turn. I don’t see this as a first ball out the bag for me but defiantly close 2nd or 3rd when the lanes start to hit that transition and I’m starting to make that move left to open the lanes up. Not to mention the colors going down the lanes how can you now notice this ball!! This one ball i feel I’ll decently see a lot of them going down the lanes.

    Exotic GEM Review

    Posted by Sandra McIntire on Feb 7th 2023

    The new Roto Grip Exotic GEM is my absolute favorite ball on the market right now. I am higher speed, rev challenged 220-250ish, high tilt, high rotation, and super low track player. The Exotic GEM took me by surprise with its ability to perform. I generally gravitate to balls with fresh surface on a fresh house shot. But, let me tell you this ball has been a game changer and I have been able to start out with it game 1 and use it all the way through game 3. I drilled my Exotic GEM 5x3x2 which is a very strong layout that reads the midlane and comes strong off the spot but yet continuous. This ball hits the pins like a freight train and I love it. I have also used the Exotic GEM as a compliment to my RST X-3 that I generally use game 1/2. The Exotic GEM is just so versatile that I believe everyone could find a spot for it in their arsenal.

    Exotic GEM

    Posted by BRIAN HIRSCH on Jan 27th 2023

    Ball Specs: Ball Name: Roto Grip Exotic Gem Cover Stock: Micro Trax Pearl Weight Block: Defiant LRG Core Color: Citrine/Apatite/Amethyst Finish: Reacta Gloss Layout: 5X4X1.5 Bowler Specs: Right-Handed PAP 4 7/8" Over 3/8 up Rev Rate 300. Speed at release 15 Fragrance: N/A Review: This is the new release the Exotic Gem from Roto Grip. As I am a fan of the original GEM, I was all kind of excited for this release. Throwing them side by side as you would expect I saw the Gem earlier than the Exotic Gem. The reacta gloss that is on these balls for me have the balls going really long and not seeing it read the lane. I have started to scuff these balls with reacta gloss with a 2000 pad to remove the shine and after doing so and getting some oil on the ball I found the Exotic to still be cleaner down lane and have a similar look as it’s counterpart the GEM. I do see this ball being used by all from middle average bowlers all the way up to scratch and tournament players. This ball is going to be in the bag for some time.

    Favourite ball this year

    Posted by Pierre Luc Larouche on Jan 27th 2023

    The new Exotic Gem is my discovery of the year !! With is clean reacta gloss finish, it's pass easily the first part of the lane. However, like the 900 Global Zen,with its matte color, it makes this ball really controllable. The Exotic don't give a too much hit when it's arrive on the back end like many pearl balls. It just give the right hit at the end of the lane with a big continuous motion between the pins. I can play many lines with; more straight in front of me or go to the left to pass across the lanes. It's will be the perfect house shot ball but for sure, in my bag on all tournaments that I will play this year. It's a no brainer ball ! You need it one on you bag, trust me !!! #ownit

    Exotic Gem review by Chris Pollentier

    Posted by Chris Pollentier on Jan 23rd 2023

    Roto Grip Exotic Gem Coverstock: MicroTrax Pearl Reactive (Reacta Gloss) Core: Defiant LRG core RG: 2.47, Diff: 0.053, PSA: 0.016 (15 lbs) PAP: 5 3/16 over x 5/8 up VLS Layout: 5 x 4 3/8 x 2 3/8 Dual Angle Layout: 55 x 5 x 35 Location: Prairie Lanes, Sun Prairie WI Pattern: Medium volume THS The new Exotic Gem is the pearlized version of the original Gem from Roto Grip. It features the same Defiant LRG core as the solid Gem but is wrapped in the MicroTrax Pearl reactive cover, which bucks the trend of previous pearl releases that use a weaker cover compared to their solid counterpart. But don’t be mistaken, even though the Exotic Gem has a pearl cover it’s an incredibly strong ball. The layout I used puts the pin above my ring finger and the mass bias slightly right of my thumb. It’s a fairly strong layout that gives me a little length up front with plenty of midlane read and a strong continuous backend. I typically scuff shiny balls with a 2000/3000 Abralon pad, but given the strength of the Exotic Gem I decided to leave it at box finish with Reacta Gloss. My first chance to use it was in league on a medium volume THS. Given the strength of the Exotic Gem, I was required to move deeper than I typically would. Often times pearl balls become pretty over/under on league patterns given the amount of oil in the middle and dry to the outsides, but the Exotic was plenty strong enough to dig through the soup in the middle of the lane and still make a strong move off the friction without over-reacting. In fact, the further left I moved as the night went on, the better the Exotic looked as it was able to retain that much more energy – so much so that I was able to pop off 300 in the final game of league. Not bad for the first set out-of-the-box! Compared to the Gem, it’s a few feet longer and retains more energy for the back 1/3 of the lane. It’s actually a great go-to from the Gem when that ball starts getting lazy and leaving weak hits. The RST-X3 in comparison to the Exotic Gem is a little earlier and a little smoother, likely due in part to the hybrid cover on the X3. Both balls cover about the same number of boards but do it with different shapes. I think the Exotic Gem would slot right between the solid Gem and RST-X3. If you’re a high-speed low rev player, or someone that gravitates to bigger hooking bowling balls, the Exotic Gem should be your first consideration. This ball definitely needs oil and seemingly rolls much better the deeper on the lane you get and on longer oil patterns. I’m confident in saying it’s the strongest pearl I’ve ever thrown.

    Roto Grip Exotic Gem

    Posted by Michael LeViner on Jan 21st 2023

    Layout: 65 x 5 3/8 x 40 Talk about midlane and backend hook!! I deliberately drilled this ball weaker than normal after watching other review videos first, and it's still a monster. I did hit it with a 4000 abralon pad to remove some of the polish, and even at 4000 it can handle all except for the heaviest of oils. I would put this ball in the category of “new” pearls, as in, they can still handle a good bit of oil. The traditional idea of a pearl coverstock ball is that it loves dry but is allergic to oil, and that certainly is not the case with the Exotic. This ball is 3-4 boards stronger than the most recent high end asym. pearl, the RST X2.
