Roto Grip Idol Cosmos Bowling Ball

(41 reviews) Write a Review
Due to the overwhelming success and popularity of the IDOL™ Helios, we felt that creating a pearlized version using the same coverstock chemistry was an absolute must that bowlers around the globe needed. So, the Research & Development Team went to work adjusting formulas and testing the different variations of the XtremeTrax™ coverstock material in a pearlized form. All we can say is WOW, we impressed ourselves which means you will be impressed as well. Our sole focus was to create an option that compliments the IDOL Helios, meaning just a bit cleaner through the front of the lane while providing more motion and reaction down lane. Needless to say, we not only hit this one out of the park, but we also hit it into another galaxy!

    Roto Grip Idol Cosmos XtremeTrax Pearl coverstock 4000 grit Ikon core 2.49 RG and .052 differential---15 pounds. Idol's are smooth and round shape...pearl or solid. If you're ever looking for a pearl ball with a benchmark shape and strength, always check out the Idol line. For me, the Cosmos might be the most angular Idol yet...but still smoother than any upper-mid level Storm/RG/900G pearls. This was a good thing for me since I thought my Idol Pearl was a bit too round/smooth for me to find a good match on any pattern. I would go to the Cosmos if I need a ball that can get a little longer downlane than my IQ Tour Solid. Or if I need a little step down from my Phaze 3 (still my favorite Storm ball).

    The Cosmos is definitely a cleaner easier to get down the lane addition to the Idol line. Customers who are big fans of the Idol's are loving it but this one is also appealing to one's who weren't as successful with the Idol line. It seems to take very well to polish and gets even better with it!

    Roto Grip Cosmos review by Brian Watson Lets start out by saying I am a huge fan of the RG IDOL line. The new release in the line is the IDOL Cosmos. RG used the Pearl Xtreme Trax cover on the very good rolling Ikon Symmentrical Core. As strong as the Idol Helios was the Cosmos to me is very smooth and controllable. I drilled mine 4 x 3 x 1 .75 pin up. Compared to the Idol Pearl the Cosmos is much smoother and longer. More of an archy motion with decent response to the friction. Where the Idol Pearl was stronger overall than the Cosmos. I will be able to use the Cosmos on a variety of the medium and shorter patterns as it so predictable and not as early as the Helios. But it does create a great 1-2 punch with Helios and Cosmos for the RG line. I drilled a 3 inch pin for a higher rev guy and he loves the control on his normal wet /dry league pattern. Carry was good and the availability to stay lined up for awhile without having to move a lot of boards. Another great addition to the IDOL line! PAP - 4 up 1 1/8 MPH - 16-17 TILT - 17 RPM - 400

    The newest Idol, the Idol Cosmos, will be a great compliment to the Idol Helios. In my eyes, the Idol Cosmos is a great combination of the Idol Pearl and the Idol Synergy. This ball is extremely versatile, I can play up the boards when the pattern hasn't quite been developed, or I can move way in and hook the lane with the best of them. This ball will be a great addition to the Idol line, this ball will be in my bag wherever I go! Go out and get yours today!

    I drilled up the COSMOS with an experimental pin position of 6" from the PAP. The pin buffer is about 3.5" away. So I expected by the layout and the composition of the ball to see it as smooth that I could probably use as a great middle control ball. This layout and ball is exactly that. I can get the COSMOS thru the fronts rather easily and still get a nice controlled arc in the back end. I have used this as a ball down option from my INFINITE PHYSIX when the PHYSIX is starting to get a little too sideways in the back of the lane. I can also cut my angles down and sort of line this one to the pocket and have it hold line to give me another option to attack the lanes. Think smooth and controllable with this one and you won't be disappointed.

    Loving the Idol Cosmos.. This ball features the iconic Ikon Core wrapped in the REX Pearl Coverstock. This set up provides clean ball motion through the fronts with some controllable motion in the back end. This ball has been the first out of the ball for league so far. On the fresh I am getting some great length and solid ball motion down lane. So far loving this ball and might be my favorite Idol yet

    Hey everyone, I'm back with another ball review, and this time it's for the Roto Grip Idol Cosmos and In 15 pounds this ball is wrapped in the REX Pearl Coverstock and comes 4000-grit polished with an RG of 2.49 with a Diff of .052 with a layout of 5x3x2. I will start this review out a little bit differently as most know I wasnt a fan of most of the IDOL balls. Not that they were bad, they just didn't match up to me. I am blessed to be a part of SPI and feel it is my job...I take that back. It is my responsibility to throw the balls and it doesn't matter if I match up or not I can provide you with the info that I got from the ball. Now if you have read this far this is where you think I will now talk about how bad it is for me, but that couldn't be further from the truth. Let me just say this first! This is the first of any of the IDOL balls that my eyes saw the way my eyes like to see a ball shape. After a few shots I was joking with my teammate and asked him if this really said IDOL on the ball. LOL. This ball took surface changes and polished very well and I'm starting this review with that info because a ball that does this is one you can put your favorite layout on and go hit the lanes. Now for me this is my auto ball down from new releases like the Infinite PhysiX and stronger balls like this. With more oil I can stay in the Infinite PhysiX for a game - game and a half and then need to go to the Cosmos. Our other center that is dryer I can throw the Cosmos for about a gameish before looking to ball down. This ball can be used on league and tournament shots as well.

    Roto Grip Idol Cosmos Coverstock: XtremeTrax Pearl Core: Ikon Layout: 5 x 3 x 2.5 I did some of my best bowling last season with the Idol Helios. The Helios has a solid version of the Cosmos cover. Out of the box, I found the Cosmos very smooth and round. That would be fine for sport patterns but going into league season, smooth and round did not look good in my home center. To make it more immediately useful, I applied Storm Step 2 for a polished, cleaner look. With this slight surface tweak, I find this ball to be a first game of league type ball. It handles the buildup of volume inside quite well and the round nature of the cover/core allows for some blending action when I miss right. I have had quite a few league nights so far this year where I was able to throw this Cosmos all 3 games just paralleling my eyes and feet left. As always, you can't go wrong with an Idol!

    The all new Roto Grip Idol Cosmos bowling ball features the Ikon Core and the pearlized XtremeTrax coverstock, which should result in a cleaner motion through the front of the lane while providing stronger reaction down lane. I have seen so many different Idol bowling balls roll very well for wide variety of bowlers. Personally, I haven't had much success with the Idol series. I have tried several layouts on different Idol's and just couldn't seem to find the sweet spot. I drilled my Idol Cosmos with my usual pin-up layout: 65 x 5 x 30. I expected this ball to flare a good amount and, due to cleaner coverstock, I thought it could be a good transition ball when stronger asymmetrical bowling balls start be too much. The Idol Cosmos is a very "rolly" and "forward" to me. I was expecting a little more response in the friction out of this ball. For my ball roll and the layout I chose for this ball, it seems to be "in between" – too much flare to keep it online, to "forward" to open up the lane. I did find a decent use out of this ball on shorter patterns, where I really needed to slow down the backend motion. I can see this ball being pretty good on shorter "house-shots" as well. I would, perhaps, drill another Idol Cosmos with a pin-down layout and use it as a "specialty" ball for shorter oil patterns. Want to see me throwing the Idol Cosmos?

    The Idol line was SO Amazing in the beginning with the first 3 domestic releases. I much of a fan the few in the middle, but with the NEWEST inception of the Idol, the Cosmos, I am seeing this to be very versatile. The Idol Cosmos while being a peal, has a very heavy nano load. It reads the mids well with a strong but not necessarily angular motion. This ball takes well to surface adjustment. the more surface, the more it blends the dry but with polish, this thing can get after it down lane! My layout is pin up, 4x5x2! Other balls getting a lot of play: Dark Code-4x6x2 Night Road-4.5x4.5x3.75 RST-X3-4x5x2 Wolverine Dark Moss-4.25x5.25x2

    Roto Grip Idol Cosmos Ball Review Rev Rate: 375 Ball Speed: 15-16 mph PAP: 5 inches over, 1/2 inch up Layout: 45x5x30 The Idol Cosmos is the fifth installment in the Idol series stateside. In testing this ball, I found it to be buttery smooth and very deliberate with its downlane motion. I was very surprised at this because I had envisioned it doing something else...like more of the Idol Pearl than a bigger version of the !Q Tour. But I love it! Its almost like OG Idol meets a touch of the Idol Helios...the smoothness of the OG with a sprinkle of the slow strong nature of the Helios. It's another piece of versatility that's on my "bowling rack" to add to my bag for leagues and tournaments. Another popular Idol to bang out high scores!

    Most versatile release this year for me. Drilled 65 x 3.5 x 30 close to my house shot layouts gives me a smooth and predictable shape and motion during league and most local tournaments. Compared to my Zen it dug in the mid lane sooner due to the 4k Fast cover. Definitely a slight step up. Slightly less than a Helios with the same carry percentage Performed well from multiple angles on the 40' Dutchman pattern thus the versatility of the cover combined with the Ikon core. Should be apart of your league and tournament arsenal this fall. #SquadRG #stormnation #GoGlobal #iambowling Keith Cordy 900 Global Staff Ambassador

    Drilled this ball with the pin over the bridge with measurements of 4 3/8 by 43. Pretty similar to how I have drilled previous pearl balls (Zen to be specific) looking to get a slightly different motion and that's exactly what I got. The pearl coverstock has a little surface to it so it doesn't have a quick motion off the dry, but instead it's very controllable, very round, while not sacrificing continuation. Took this ball out right after drilling for a couple games on THS and was able to play a couple different parts of the lane. Was able to keep my angles in front of me with a little extra ball speed, and move left and circle it through the oil with a very smooth backend motion. If you are looking for an extreme hockey stick, this is not the ball for you, but if you want a controllable and versatile pearl ball, this will be a great add to the bag.

    Ball Review Idol Cosmos, RG: 2.49 Dif: .052 Cover: ExtremeTrax Pearl 4K Finish PAP 5 1/8 over ¾ UP, Medium/Ball Speed Rev Rate 275-325 Layout: 4 x 4 x 1 ¾ The return of a Pearl addition to the Idol lineup and definitely a nice surprise. The Cosmos is a great addition to the pearl line up. It has the performance that bowlers expect from the idol line. It's smooth and rounded shape is very predictable. It has a strong backend motion with good continuation from the pins. The Cosmos with the ExtremeTrax Pear cover at 4k finish responds hard off the friction but doesn't seem to overreact. The Cosmos picks up down lane and holds its energy well. The Cosmos will fit most play styles and conditions. Definitely recommend this ball if you are looking for a new smooth ball with a strong backend pearl.

    The Idol Cosmos is the newest edition to the Idol line. It features the same core as all the previous Idol balls but is now wrapped in XtremeTrax pearl. For anyone that loved how the Idol pearl shaped but wished it has a little more teeth in oil or for someone that loved the OG but didn't like how it shaped from farther left, look no further. The Idol Cosmos showcases the best of both worlds by providing enough control for the fresh but enough shape to allow you to open up a lane before going to quicker response balls. The Idol Cosmos for me will be fantastic on fresh house shots or a great three ball during a longer tournament block.

    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 2: 4 ½ x 4 x 4 1/8 (pin below bridge) The Idol Cosmos is an updated version of the Idol Pearl. It's got more additive in the cover and rolls earlier while maintaining the shape on the backend. The Idol Pearl got a little "squirty" in oil and the Idol Cosmos solves this issue with the stronger cover. It never wants to miss the midlane so I feel I can use it earlier in a block. This one is simple, if you like the Idols, this is another great one!

    Roto Grip outdid itself once again with the newest addition to the Idol series. The Idol Cosmos, for me, is a great one-two punch to the Idol Helios. Since the Cosmos is a pearl cover, it will save more energy for the back part of the lane. The Helios is a little earlier, so when I have to move left, then switching to the Cosmos becomes valuable. I have the Cosmos drilled pin over my bridge with the CG kicked 1' to the right. Very pleased with this ball, it gives me a nice, predictable motion.

    Roto Grip Idol Cosmos Layout: 45 x 4 ½ x 45 The Idol Cosmos, despite it having a pearl coverstock, has become my current benchmark ball. With the stronger composition of the cover, and the 4k-fast finishing process, this ball is in a different universe of ball reaction than that of the previous Idol Pearl. The Cosmos has enough midlane traction to handle medium-heavy oil patterns, though it is also clean enough to be used on medium to medium-dry conditions. I would categorize the ball reaction as being smooth but with some backend kick. It is one of the most versatile pieces that I have seen in quite some time.

    Ball Specs: Roto Grip Idol Cosmos Cover stock –Pearl Reactive Symmetrical Core Color Stardust Teal Finish 4000-grit Abralon Layout 45 x 4.5 x 45 Bowler Specs: Right Hand. PAP 5" Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at camera 15.5 Review: The new Roto Grip Idol Cosmos is a very good ball. I like the motion and total hook of the Helios but sometimes it is too much ball for certain conditions. The Helios is hard for me to see transition due to the color I think, so I use it took long before balling down. The new Cosmos is unique because it has the same feel as the Helios even though it has a cleaner and more angular motion and hooks less overall. I can easily see when this ball makes its move also. I have had pretty good luck with the Idol line but the last two have been my favorites. I still use the Synergy on some occasions also. The Idol Cosmos seems to play best for me on medium conditions and I like this ball in box finish or polished. I probably lean on the polished version more than the box finish where I normally bowl. This Idol Cosmos is different than the Helios in the fact it goes longer and makes a stronger move at the break point. I am not a high rev player, but I am able to move inside on different conditions and still maintain excellent carry. It's nice when a guy like me can get those extra corner pins to fall. Summary: The Idol Cosmos has a very good and unique motion. The Cover sands and polishes easily for dialing in a shape on the lanes. The hit is very good due to the entry angle.

    The Idol Cosmos is the newest addition to the HP3 line of balls. This ball comes that 4000 abralon. With this OOB surface I found that this would be a great ball for something that would be around game 2 or 3 of league. This ball gave me a great controllable shape on patterns that aren't too broke down. Similar to the Idol Helios this ball will give you a arcing move on the backend allowing for great control from multiple angles. This will be a great ball on multiple patterns and the surface will be great to play with depending on the conditions Alex Thomes #StormNation #SquadRG #StrikingWorldwide #Driven2Bowl

    The new Idol Cosmos from Roto Grip features the XtremeTrax Pearl Reactive coverstock wrapped around the Ikon Core! My Idol Cosmos is drilled pin over my bridge and allows me to have a Pearl ball in my bag that is smoother off the spot during transition! The core in the Cosmos has always been a stronger core and with the 4000 surface on the surface allows it to be more controllable when a Zen, Wolverine Dark Moss, UC2 are to quick off the spot!

    Roto Grip Idol Cosmos Layout: 60 x 1 1⁄2 x 60 Finish: 4k FAST Lane types and pattern types: HPL lane panels with 48ft THS pattern and SPL panels with 46ft THS. I decided to drill the IDOL Cosmos with one of my favorite THS killer layouts. I bowled in 2 different centers with vastly different lane surfaces and overall length and volume of the THS. So, while my main ball out of the bag to start has been the Roto Grip HYPED Hybrid for about 9 months now, I was missing that later motion but not super flippy like a Hyped Pearl or even an Electrify Pearl. Normally, as the night of league matches goes on, The Hyped Hybrid is very clean and carries a TON, it actually is still at 1500 grit polished and I am determined to leave it that way, because if it is not broke, don't fix it, but as the matches progress, I would find I would need to have a smidge longer length before it would start to make any direction changes, I tried an Idol Pearl, 2 Hyped Pearls, (2 in P2P and a 6 in P2P) in 1500 grit polished and 4K Fast and even my own rendition of 4K FAST with finishing it with a 5000 grit pad, nothing seemed to get me over that mid match hump, until the Roto Grip Cosmos came along. Was able to project outside where the other lefties were playing, was able to open up the angles and even close down the angles and play relatively straight with the Cosmos.

    The newest addition to the idol line the idol cosmos. This ball comes in 4k fast and for a pear is very clean down lane i drilled mine with the layout of 40 x 3 x 60. My goal was to get this ball to stand up faster with my loft and still continue off the spot. Compared to my helios this ball will allow you to move left when doesn't make it back.

    Ball Specs: Roto Grip Idol Cosmos Coverstock: 4000-grit Xtreme Trax™ Pearl Reactive Weight Block: Ikon™ Core (Symmetrical) Color: Stardust Teal Review: Speaking of some of the most iconic lines in bowling history the Idol line is right up there with the best of them. The idol Helios was a great addition to the line, and they followed it up by introducing the Idol Cosmos. The Cosmos allows you to have a similar motion as the Helios with a pearl cover stock. When the lanes start to break down I pull the Cosmos out and still have the confidence that I am going to get a similar reaction as my Helios. The 4K Fast finish doesn't affect this ball at all, you still get that pearl reaction. Don't forget about the appeal this ball really stands out on the lanes.

    Core: Ikon Coverstock: XtremeTrax Pearl Finish: 4000 RG: 2.49 Differential: 0.052 ME: Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 PAP: 4 7/8 Right 3/8 Up Ball Layout: Pin Up 5 3/4 Pin to Pap 1 inch pin buffer With all the honor scores that the Idol Helios racked up, and my own success with the ball I couldn't wait to get my hands on a pearl version. I wasn't disappointed when Roto Grip releases the Idol Cosmos with the same Ikon-ic core shape and the XTREMETRAX™ Pearl Cover. What was already an incredibly continuous ball motion is further enhanced with the additional length provided by the pearl additive. The cosmos provides an ideal transition piece from the Helios and makes it easier to get the same reaction when the heads go. I tested the Cosmos on the high volume 43 foot house pattern at my home center. The cleaner cover did play a little more friendly closer to the friction. While there's lots of volume there is plenty of shape to this high ratio pattern. The helios is so dynamic I definitely preferred playing the hold to playing the friction. That being said I definitely prefer the Cosmos after a game or so, when the hook spot has had more time to develop. It is useful with straighter angles out of box, but where this ball really shines (pun intended) is when you polish it up and open your angles with it. It's makes a great, quick move that generates great angle through the pins when you have to get steeper through the front of the lane.
