This pearlized version of the XtremeTrax coverstock combined with the Ikon Core provides a cleaner option through the front part of the lane and then generates more motion and backend reaction on medium to heavy oil conditions.

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!

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.

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!

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 XTREMETRAXâ„¢ 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.

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.

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 new Idol Cosmos features the same successful Ikon core and wraps it in the Xtreme Trax pearl coverstock.  The Idol line which has been hugely popular and successful, has another winner with the Cosmos.  This ball comes finished at 4K fast (4000 grit abralon) and can be easily adjusted to fit the bowler’s needs.  Out of the box, the Cosmos’ pearl coverstock allows it to be clean thru even the most burnt heads and the Ikon core provides the consistent smooth backend that has been a trademark of this line.  The Cosmos has one of the smoothest backend reactions I have seen out of a pearlized ball. This ball is a great compliment to the Idol Helios.  For me the Cosmos is about 4 to 5 boards of less hook than the Helios.  It is a great benchmark ball and is also good on the typical wet/dry house patterns.
