Exotic Gem
« on: February 10, 2023, 09:49:06 AM »
Following the success of the original Gem, Roto Grip presents the Exotic Gem. This high-performance ball utilizes the pearl version of the MicroTrax coverstock and pairs it with the same Defiant LRG core. This core and cover combo produces a ball that will skid through the front part of the lane then dig into the middle of the lane then produce powerful continuation at the back of the lane. The Roto Grip Exotic Gem is a high-end asymmetric pearl ball that performs best on medium/heavy oiled lanes.

Color: Citrine/Apatite/Amethyst
All colors do vary somewhat from the picture shown
Coverstock: MicroTrax Pearl Reactive
Core: Defiant LRG (14-16#)
Finish: Reacta Gloss
RG: 2.47 (for 15# ball)
Differential: 0.053 (for 15# ball)
Recommended Lane Condition: Medium/Heavy Oil
Hook Potential: High
Length: Middle

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!

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.

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 Ball Review
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.

COMMENTS

Likes: More useable than the Gem

Dislikes: Nothing!

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

Roto Grip Exotic Gem

Length:43ft

Volume: 25.5 mls

Type (THS, Sport Pattern etc): THS




Likes: So if I’m going to be completely honest when I first drilled the Exotic I wasn’t too big of a fan and I couldn’t figure out why because typically I love balls like this. So I put it in “timeout” to come back to at a later date. So a week or 2 went by and I made a pretty big fit change so I figure my test ball would be the Exotic. I ended up shortening my span 1/4 of an inch and I could immediately tell that it made my roll a little more end over end. But during league that was the only ball that I had at that fit. So I said screw it and decided that I would try and make it work. Well game 1 I ended up shorting 300 with it and what I noticed was that because I was rolli my it a little more end over end it made it wanna pick up a little sooner and roll through the pins just slightly different which made all the difference. Now the exotic doesn’t leave my bag for league or for tournaments and I will end up drilling another one here very shortly. And if you need a slightly bigger ball but with a pearl cover than this is the one I would recommend over and over again!

Dislikes: Not anymore! But if anything a little bit too strong at times haha

Storm Roto Grip Exotic Gem by Casey Murphy
« Reply #22 on: May 13, 2023, 02:10:16 PM »
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 Exotic Gem is a new pearl Gem from Roto Grip.  It features MicroTrax Pearl, which is pretty strong for being a pearl.  This makes the Exotic Gem clean enough to use on some lighter volume patterns or some transition but it still has plenty of teeth to get around the corner.  I was a fan of my Gem with some lane shine, so I was ready for a pearl Gem that would be even a little cleaner and more responsive.

Roto Grip Exotic Gem

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!

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!
