Roto Grip Exotic Gem Bowling Ball

Yikes the Defiant core with a reactive pearl coverstock. Yes lets go this ball is already a favorite. I was happy with the original gem but it was a little much for me. But this exotic gem is what i was needing. This ball is giving me a different shape for me down lane that i was missing and needs. The core rolls heavy up front but the pearl lets it get through the fronts. Down lane for me it def reads the friction but seems to set up for me and really gets through the pins well. I have thrown this with success from house to middle volume sport shots. love this gem

First, the Defiant LRG core brought a well-defined motion to the original Gem. Then building from the Defiant LRG's success, Roto Grip combined it with the MicroTrax Pearl reactive coverstock. And this proved to be a winning combination making the Exotic Gem a phenomenal new release. So, with its brilliant results, let's take a closer look at why the Exotic Gem belongs in your arsenal! The Defiant LRG core is a big and beefy asymmetric core. And as down and in player, I like that the Defiant LRG has a robust and decisive motion. But unlike other bulky asymmetric cores that tend to become angry and violent in their motion, the Defiant LRG revs smoothly. And impressively, it has a more methodical attack behind its roll. And when the Defiant LRG stood up and headed to the pocket, I was impressed with its powerful impact as it struck the pocket. And being a low-rev player, I loved the strong and continuous roll I saw with the Defiant LRG, as it makes the Exotic Gem a continuous crushing machine. The MicroTrax Pearl reactive coverstock delivered success to the Exotic Gem's outstanding potential. I found the MicroTrax Pearl provided biting traction early in the midsection. And although I liked its aggressive nature, I loved how the MicroTrax Pearl was smooth off the pattern. The MicroTrax Pearl reads earlier than you would expect from a pearl, but I liked how it maintained a well-defined motion as it made its way toward the pins. Now, being a straighter player, surface is my friend. And for my speed and rev rate, the Reacta Gloss finish needed some tweaking for a THS league night. So, I sanded my Exotic Gem to 1500-Grit Abralon and followed it up with Storm Step 2 finishing compound (320-1500 grit.) And this surface adjustment made the Exotic Gem fun to roll all night long. Early on, I could play my A game - rolling up twelve with a powerful down and in motion. And as the night went on and the lanes transitioned, I thoroughly enjoyed being able to move my angles in and not stress over it. And even with my weak rev rate, the Exotic Gem retained plenty of energy that exploded at the pins. So, for me, the MicroTrax Pearl reactive coverstock was the missing ingredient to kick out the annoying tens pins I left with the original Gem. In conclusion, the Exotic Gem is an excellent release from Roto Grip. And for down and in players, the Exotic Gem is smoother and cleaner than the original Gem and retains much more energy. And with the right surface adjustment to fit your speed, style, and rev rate, the Exotic Gem is a powerful weapon to add to your arsenal. So, talk with your local Storm VIP Pro Shop Operator and have your Exotic Gem ready for tonight's league. And be prepared to crush the competition!

One of the latest additions to the HP4 line at Roto Grip is the Exotic Gem. From a shelf appeal standpoint, this ball is loud and flashy. From a performance standpoint, it strikes a TON! I’ve been very impressed with the Exotic Gem thus far and continue to take it with me to all types of events. Similar to the original Gem, the engine inside is the Defiant LRG core, but the biggest difference with the Exotic is the coverstock. Big Schlem and the minds in Utah created a pearl version of the MicroTrax coverstock and wrapped the Exotic Gem with it. I’m a big fan of the Exotic Gem and drilled it with the following numbers: 5 x 4 x 2. This puts the pin above my bridge, a slight shift of the CG, and the mass bias is just to the right of my thumb. I’ve had the most success when using this ball on medium/longer patterns with heavier volumes. The Exotic Gem is strong enough in the mid-lane and down-lane to still create shape and go through the pins the right way. Once my Gem has done it’s job and it’s time to put in the bag, the Exotic Gem is the perfect ball to use. I’ve also adjusted the surface for those heavier volume conditions. By hand, I used a 1000 pad to create a bit of an earlier shape but to slow down the response time a bit too. If you need a ball that digs, continues, and is a perfect complement to the current lineup, go drill an Exotic Gem!

The new Roto Grip Exotic Gem features the same Defiant LRG core found in the original Gem, but wraps it in the Micro Trax pearl reactive coverstock. The 15 pound version features a low RG of 2.47 with a differential of .053 and an intermediate differential of .016. With my slower ball speed, I was looking forward to this release. I drilled mine 5 x 4 x 2 which puts the pin above my middle finger. The Exotic Gem is a fantastic complement to the original Gem. Both balls have that early rolling heavy roll making them very controllable on harder conditions. For me the Exotic Gem went about 2 to 3 feet further down the lane with a much more angular backend motion than the original. For my game, the original Gem was just too much too soon. The Exotic is a ball I can throw on just about any pattern as long as there is oil in the front half of the lane. This pearl does not shy away from oil, and although it is more angular than the original, it is very controlled arcing motion for a pearl coverstock. This is a ball that will get a lot of lane time on medium-heavy conditions for me. This is a great pearl ball for tougher conditions.

Exotic gem review Storm VLS 5 3/4 × 3 1/2 × 1 3/4 I was looking forward to this release as I liked the original Gem but couldn't use it as much as I would like because of how early it rolled. And usually when I like a solid version of a Roto Grip ball, the pearl does not disappoint. The Exotic Gem reads the lane a little earlier than other pearl balls I've had recently but it very easy to get lined up with. I find it to be versatile in that I can play straighter on the fresh if they are tighter or go to it later in a set when I have to open the lane up. It's a ball I can often throw for 3 games in league, which is rare these days to go without a ball change. I can just chase a little left and keep a similar line. It has no problem recovering on the shots that go right but will still grab enough in the oil to be ok. Compared to my RST X2, the Exotic is a little earlier but definitely stronger off the spot. It will obviously be much cleaner than the original Gem but the shape will be familiar. This ball has been a league killer, putting up consistently good numbers and again I can use it all night. Because it is so strong, it may burn up if too far in the dry, but moving left it will store some energy and get you right back in it. This is also a ball that everyone I know seems to like, regardless of different styles. You can't go wrong with this in your bag. Dave Adams Storm staff

As an experienced bowler who has had the opportunity to test a wide range of bowling balls, I can say without hesitation that the Exotic Gem Bowling Ball from Roto Grip is a must-have for any serious competitor. In fact, this ball is the first one out of my tournament bag. The MicroTrax Pearl Coverstock and the Defiant LRG Core work together perfectly for me, as I have been able to use the Exotic Gem on a variety of different lane conditions. The ball has been very easy for me to use because it has a very predictable motion. The Exotic Gem has reacted well for me whether I was playing the 4th arrow or the 7 board. In a few events, I have started with the pearl asymmetric Exotic Gem and then transitioned to the TNT, which has a Solid Cover and symmetrical weight block. That is an interesting combo for me. In short, I can't recommend the Exotic Gem highly enough. This is truly a great ball, and I will drill a number of them over the coming months and years. https://www.youtube.com/watch?v=mqjkUDUcOKY&t=8s

The Exotic Gem is a new piece from Roto Grip that features the MicroTrax Pearl Coverstock. Being a step down from the original Gem, this piece is something you need after those big asymmetric solids like the Gem, Reality and Super Nova. The cover allows the ball to get through the front part of the lane very well with a lot of mid lane control and a lot of pop in the back. If you’re a higher speed dominant player or a straighter player, or just in search of a step down from those big asymmetric’s, this is the ball for you!

The all new Exotic Gem features the same Defiant LRG Core wrapped around the MicroTrax Pearl Reactive coverstock with the Reacta gloss finish. This ball has pleasantly surprised me, I am typically not a fan of the low RG asymmetric pearls, however this ball seems to be something special. This ball gives you the strong controllable motion you saw from the Gem, but the coverstock allows you to open up your angles and strike when the original Gem struggles to get the corner pins out. I have seen some success with this ball already and I fully expect to have this ball in my bag for the foreseeable future. If you have not gotten this ball yet, you need to go out and get yours today! Layout: 40 x 5 ⅜ x 25

The Exotic Gem offers the strongest core in the Storm Products umbrella with a super low 2.47 RG. With that super low RG, the core stands up much earlier than anything else we have but that doesn’t mean it rolls out. The core does start revving up much sooner than most in our line but continues to do that as it transitions through the lane, meaning more continuation through the pins! For me however, it does not like too much friction on the lane. It needs the oil so the ball does not start up too early. Great 1st transition ball when there is still oil in the fronts but you need a little less traction.
