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!

    The Idol Cosmos is the pearl counterpart to it's predecessor the Idol Helios. For me, it's not the usual "way longer, way sharper" shape that you expect out of any pearl version of a ball. The Cosmos is definitely clean up front, but is exceptionally smooth down lane, never giving me the hockey stick motion or anything unpredictable. It's extremely good at controlling the pocket when the lanes start to transition. I went pin up with mine (4.5x30), and I couldn't be happier with what I see. It stands up in the mids decisively and kind of calmly and predictably makes the left turn. I'm usually not a huge fan of pearls, I can truly say this is an exception.

    Roto Grip Idol Cosmos Ball Review by PJ Haggerty The Idol line from Roto Grip has been extremely successful and I've been a big fan of them since the original, pink Idol. The Cosmos is the latest release and the biggest difference is in the coverstock. The brains in Utah used a pearl Xtreme Trax cover along with the same symmetrical weightblock that we've seen over the years. The main purpose of the Cosmos was to create a cleaner, pearl version of the Idol Helios, and it has delivered. I've drilled one Cosmos so far and will likely drill another. I think I drilled the first one too strong when I drilled it with a 4 x 4 layout. This really smooths out the response time, but is still very useful. I think I'll be able to use this Cosmos on shorter patterns when I need the ball to bleed energy at the end of the pattern. When I drill another one, I'll likely drill it with a 5 x 4.5 layout to create more length and try to make it usable on more patterns. Also, I think the Cosmos will take surface changes extremely well. Kris Prather used a polished one on the PBA League shows and it looked awesome. Mine has the box surface on it and it's much smoother. Overall, if you need a cleaner, responsive ball with a low RG that will be extremely adaptable to surface changes, you should drill an Idol Cosmos!

    Roto Grip Idol Cosmos Layout: 5 x 4 x 2 Rev Rate: 325 rpm, 7 degree of axis tilt, 40 degree of axis rotation Testing information: 40 foot THS (medium to light volume) Bowling Center: Fulton Bowling Center Kegel Machine – Brunswick Anvilane The Roto Grip Idol Cosmos pairs the Xtreme Trax pearl coverstock with the proven IKON core. The Idol Cosmos makes a statement – on the lane and on the shelf. I like the green color of the coverstock. The ball just looks like it will perform well. During testing, I definitely got an Idol Pearl vibe. I would say it may be a touch stronger than the its pearl predecessor but similar in ball motion. When tested against the newly released Storm Infinite Physix, the Idol Cosmos was cleaner through the front part of the lane and retained more energy for a more defined hook motion down lane. The Idol Cosmos is going to be a good one folks. If you are missing your Idol Pearl, this is an option for you. Visit your local Storm VIP Pro Shop! #Stormnation #SquadRG

    Another Idol, another homerun. Roto Grip introduces the second Idol coming back into the Idol Series, the Idol Cosmos. This ball has the Xtreme Trax Pearl Reactive Coverstock wrapped around the Idol core we have all come to love. What's special about this ball is that it is not your typical skip-flip pearl. The Xtreme Trax Pearl coverstock maes this idol have a more rounder and smooth shape throughout the lane. This is huge for the Roto Grip line and for more advanced bowlers that are looking for a stronger pearl but not something that's going to get down the lane and go sideways. This ball is going to come into play on wet-dry house shot conditions and for the flatter patterns that players see on the regional and national PBA Tour's. Predictability, reliability, Idol Cosmos.

    The idol line continues to come out with the best balls in any line. We all liked the xtreme cover that was on the idol helios. So it only made sense for roto grip to come out with a pearl version with the xtreme cover. This idol cosmos comes at 4000 grit not like your typical shinny ball coming from utah. If this ball hooks too soon for you, you could hit the ball with a 1500 grit abralon pad and polish it to get it back to storms original. For you more speed dominant players this ball should be money for you guys at the 4000 grit abralon, with the pearl cover.

    The Idol Cosmos is the newest pearlized Idol to hit the market. XtremeTrax Pearl is the strongest pearl coverstock on an Idol to date. This ball is a great compliment to the Idol Helios, its cleaner and sharper. The Idol Cosmos is a great ball for when the lanes start hooking. The strong coverstock formula allows this ball to go across the pattern and still make the corner. Go to your local pro shop and pick one up today! YouTube Channel: Millennium Bowling Supply

    The latest Idol (Cosmos) is a pearlized version finished at 4000 grit. Much cleaner than the Helios yet smoother than the original Idol Pearl; in part due to the coverstock finish. The ball reads the mid's very well although not as strong as you would see with the Helios. The Cosmos will be a great step down from the Helios or an initial ball if your looking for a reaction that is cleaner yet still smooth. If you're looking for more angle and a more skid snap reaction add some shine to it to open up your angles and get deeper on the lane.

    Ball Specs: Roto Grip Idol Cosmos Coverstock: 4000-grit Xtreme Trax™ Pearl Reactive Weight Block: Ikon™ Core (Symmetrical) Color: Stardust Teal Review: The Idol line continues to pump out bangers! We loved the Xtreme cover found in the Idol Helios and so did many of our customers. Having a pearl version of this cover feels like cheating! We threw some polish on the cover to push that reaction further down lane and we are loving the shape We hope the timing of this release doesn't keep people from trying our this ball because it really is something special. If you have purchased any of the Idol line of bowling balls then this is a must have. This is also a unique shape to put into your tournament bag. Great job SPI!

RG • 2.49 Differential • .052 Layout •4 x 4 x 1 ½ Tester PAP • 5" R, 5/8" D Tester Axis Tilt • 11° Testers Rev Rate • 325 Test Pattern • 42' THS (Typical House Shot) • Modified, Kegel Stone Street Roto Grip continues their legendary success of the Idol line with the release of the Idol Cosmos. And at the heart of the Cosmos is the proven and reliable Ikon Symmetric Core. Combined with the all-new XtremeTrax Pearl reactive cover, the Idol Cosmos not only performed with exceptional results but also has a versatility that makes the Idol Cosmos a strong choice for your arsenal. So, let's take a closer look at how the Idol Cosmos delivered on a THS! The Ikon Symmetric Core debuted in the original Idol line and is a well-balanced core. This low Rg symmetric has a smooth dynamic roll through the mid-lane. And its high differential delivers a strong flare giving the Ikon Core a smooth, dependable motion for many different style players. Specifically for straighter players like me, you will love the Ikon Cores' ability to get down the lane while retaining an intense amount of energy that explodes through the pins. And for those rev-challenged players -the Ikon core maintains a strong continuation to kick out those annoying single-pin raps! The new Xtreme Trax Pearl Reactive cover is what makes the Idol Cosmos stand out! This emerald Pearl Reactive cover has a firm bite in the front part of the lane, and I loved how it had a clean transition at the back end. Of course, being a pearl, it goes longer down the lane than its solid counterpart found on the Idol Helios. Yet, being a straighter player, I found the Xtreme Trax Pearl blended the skid, hook, and roll phases smoothly and distinctly all night on a THS. That type of predictability makes the Idol Cosmos an excellent choice for bowlers with a higher speed and lower rev rate like me. And the 4000-grit Abralon finish was ideal for your typical night of league bowling. In conclusion, the Idol Cosmos is an all-around great new release from Roto Grip. Straighter and more conventional type players like me will enjoy the predictability and comfort the Idol Cosmos brings to your game. Further, the Idol Cosmos will deliver results by itself, but when added with an Idol Helios and a spare ball! Then, you have a great THS arsenal to give you that competitive edge all season long. So, visit your local Pro-shop operator today and see how the Idol Cosmos will complete your arsenal! It's worth it! Rick Klimowicz Storm Products Pro Shop Staff Roll the Ball Pro shop Penndel, PA

    Layout 4 ½ x 30 Surface – 4k fast The new Idol Cosmos brings back the Ikon core with the Xtremetrax Pearl Coverstock. The Cosmos is a nice step down from the Idol Helios which has the Xtremetrax Solid Coverstock. At the new 4k fast finish, the Cosmos tends to be a little more smoother then what you would typically see in a pearl ball. Depending on the conditions you bowl on, this finish can be pretty beneficial for you. If you prefer that more skid flip reaction, put some Storm Reacta Shine on it for a longer and more angular motion. Test pattern: 2022 USBC Masters When throwing the new Cosmos on the USBC Masters pattern, I saw a lot of midlane roll and continuation down lane. The 4k fast finish didn't make the ball sensitive to bowl the oil and the friction. Even with the higher volume on this pattern, the ball had no trouble continuing well through the pins. Comparative to the Idol Helios, I saw slightly less midlane roll with more backend motion. The Cosmos allowed me to open the lane up more then the Helios due to the coverstock differences. As the pattern broke down, the smoother 4k fast finish didn't quite produce enough angle down the lane as my feet got into the 30 board range. Putting polish on this ball would allow me to play more angle if preferred. At the current box finish, the Cosmos would have more success on fresh to first transition on the lanes.

    The ever so popular Idol line has been a hit since Roto Grip announced the original Idol in the HP3 line. This Ikon core ball is wrapped around the XtremeTrax pearl cover. This ball has a 4000 grit box finish. I drilled mine 5.5 x 5 x 3 and I will be comparing it to the ever so popular 900 Global Zen and my Idol Helios. Now my first few shots with this ball I actually had it very similar to my Zen. They kind of made the same shape and picked up the lane in similar parts. I feel like it revs up quick in the mid lane and makes a smooth motion towards the pocket. Now I normally hit my Zen with 2000 so if it was shinny I bet I would see more of difference in shapes. Now compared to my Helios the Cosmos is a little cleaner but the motions are similar. I can see myself using the Cosmos right after my Helios. It controls the mid lane really well and doesn't over react in the dry.

    The Idol Cosmos will be a ball I throw for a long time. I can't get it out of my hands ever since drilling it last week. In my ball review I compare it to the Wolverine, and I have the Idol Cosmos a little bit weaker overall and cleaner through the fronts. It's going to be a great compliment for those that still love throwing the Wolverine. The Hustle Camo is even weaker than the Idol Cosmos, but I can see those three balls being used consecutively later in a block or on a house shot that hooks quite a bit. Don't be afraid to polish this ball if you need a little more length out of it. I think it will be a great choice for you either sanded or polished.

    Idol Cosmos - Ball Specs Cover Stock: Extreme Trax Pearl Reactive Finish: 4000 Grit Core: IKON Core Layout: 65 x 5 x 35 RG: 2.49 Differential: 0.052 Review The Idol Cosmos is the newest pearl ball in Roto Grip Idol line. The Cosmos has the fan favorite Ikon Core with the Extreme Trax pearl reactive cover stock. That combination of cover and core make it great one two punch with Idol Helios. For me the Cosmos is a great replacement for the Storm Phaze 4 Pearl. The Cosmos is clean through the fronts but reads the midlane sooner than most pearls with a strong motion on the backend. This ball is very versatile. I was able to stand to the right and left of the track area without losing any hitting power. I tested this ball on a 42 feet typical house pattern. This is a great ball for levels of bowlers. Order one from your local pro shop today! My ball review videos are posted on YouTube channel Stanley Waite.

    Idol Cosmos is a good piece for Medium Oil Patterns. Compared to the Idol Helios, the Cosmos has more length with a smooth continuous Backend motion. Good piece to go with when the front part of the lane goes away or when the lanes get over/under reaction with other pieces. Compared to the 900 Global Zen, Cosmos is a few boards more all around.

    The Roto Grip Cosmos features the XtremeTrax Pearl Reactive, the Ikon core, and comes at 4000-grit out of box. This ball was strong out of the box, stronger than I was expecting. After a few games the Cosmos lane shined up and settled down some. Compared to the Helios, the Cosmos is a step down and will allow you to get the ball down the lane easier when the Helios is picking up too early. As the Helios becomes too much ball, the Cosmos will be the ball next out of your bag. With the Cosmos being stronger and having a controllable shape, I think this ball will be good on many sport patterns along with being the first ball out the bag for most house shot leagues. The Cosmos is a great addition to the Idol line! Tobias Myers #RotoGrip

    The Idol Cosmos features the XtremeTrax Pearl coverstock that debuted in solid form on the Idol Helios, and it comes at 4000 grit. The core is the strong and rolly Ikon core the Idol series is known for, and it's a 2.49 RG and .052 differential in 15 pounds. The Cosmos is very strong and round shaping, just like the Helios, but obviously a slightly weaker version. The Cosmos feels like a stronger IQ Tour Nano Pearl that's firmer down lane, it has the control of an IQ with some extra teeth and punch. If both are at box, it's a very good step down from the Helios because it gives you the same type of look but that's a bit weaker and easier down the lane. It's a step sideways from something like the Zen, Zen Soul, and Phaze 3, because while technically it's stronger, it's also not as sharp, and would be a good ball up from something like an IQ Tour because it's the same general look and shape but in a stronger package. While the Cosmos might be quite useful for higher rev rates on easier patterns, it's better suited to tougher conditions I think because of the combination of strength and control. It could be a ball down, or a first ball on medium length and/or flatter patterns.
