Idol Cosmos
« on: July 15, 2022, 05:02:17 PM »
The success of the Roto Grip Idol line of upper-mid performance bowling balls continues with the Idol Cosmos. 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.

Color: Stardust Teal
All colors do vary somewhat from the picture shown
Core: Ikon Symmetrical (14#-16#)
Coverstock: XtremeTrax Pearl Reactive
Finish: 4000-grit Abralon
RG: 2.49 (for 15# ball)
Differential: 0.052 (for 15# ball)
Recommended Lane Condition: Medium Oil - Medium/Heavy Oil
Hook Potential: Medium to High
Length: Long

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.

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

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.

The Roto Grip Idol Cosmos features the XtremeTrax Pearl Reactive, the original Ikon core. This has to be one of the smoothest pearl balls I have ever thrown. It gets down the lane with ease, with a smooth mid lane reaction and a controlled back end. This ball works very well for me on a the over/under house shots. Has enough midlane to pick up in the oil and still carry, while also not overreacting when I hit the friction early. It also adjust to surface changes very well, as I prefer to keep mine with shine on it.

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!

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 Cosmos is definitely a cleaner easier to get down the lane addition to the Idol line. Customers who are big fans of the Idol line 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!
