Roto Grip Idol Cosmos Review
While no longer in production, the Idol Cosmos remains a solid option on the used market for serious bowlers who need a strong pearl ball for heavy oil. The combination of the Ikon core and XtremeTrax Pearl coverstock delivers impressive backend motion while maintaining good length.
[Music] ceo ron wiggler from creative difference got that brand new idol cosmos and some tech we're going to look at some tech starting off with this bowling ball service career i'm having my man billy levan scan the idol cosmos bowling ball we're going to scan that ball using the ctd ball surface scanner let's go put it on there and it's going to click the button and see what it is 2000 grit yes sir this ball is 2
000 grit so now we have an idea what we're bowling with we're going to throw some shots on specto and clutch bowling we actually have clutch bowling that'll help us see a little visual on the lanes as well and we're going to kind of see what this bowling ball is all about new ball from roto grill well she's not scared to hook that's a good thing that's a great thing to start off with so we'll have him throw some shots look at some different angles
we may even put out some stuff on here with clutch and see how she looks in the dark in the oil 10 back
60 by four and three quarter by 30 is the layout that we always use for these street ball reviews for billy levan aka billy revs gonna look at a few different views few different angles of this bowling ball looks to be pretty versatile on the house shot okay so that's a little wide right
little wide right did not recover kind of see that from the specto data there expect to kind of showing that ball the green shot was definitely a little wide right a little steep on the launch angle and obviously ball did not recover now with that being said they'll get a full rack but with that being said it's important to note that like what you're trying to do is get bowling balls that will allow you to have some room for air the more room for air you have the easier it is to strike so that means that a particular bowling
ball may be good in the environment but may not be good this kind of depends that should be a pretty good pitch there 10 back 10 back now you can see just from the data here the launch angle was not nearly as deep through the front and that allowed that bowling ball to do what it did and ultimately get a nice good strike so i'll get a high view angle now we'll go a little higher so you can see what it looks like that way
another good pitch another good pitch all right so cool let's go ahead and get in the dark share a little bit of that clutch bowling we're also going to put a little tracer on this so you can actually see that is the lane pattern that we're bowling on you can kind of see exactly what we're bowling on where he's playing oh that's important to note that light right around in this area right here that is a good spot to play because if he misses in the ball will push in the oil and if he misses out the ball recovers and is able to get back to the pocket so that's why it's important to kind of have an idea of what you're bowling on and this
is a typical house shot so you can see that shot was close just in just a smidgen and left that wrap temping i'm gonna go ahead and go over here to clutch we're gonna put a little ball effect on it we're gonna give him a little ball effect we'll do a little firework ball effect for billy there so he'll throw another shot for us we'll kind of see what it does so it appears that this
ball has got some versatility to it obviously in this particular environment it probably isn't the first ball you go to um it seems to be a little bit longer for this this pattern in this environment i probably would go to something asymmetric and a little bit stronger and then maybe boil down to this once the lanes begin to break down and that shot was aced that was a that was a really really quality shot and he left the uh four nine so that tells you he'd have to make a little bit of an adjustment if he wanted to strike which will have him do that but that's what i mean like this ball it's great but it's not great for this
environment i would not be using this ball in this environment once the lanes begin to break down i probably would go to something like this but the fact that you know he went rap 10 and then four nine that tells you this is kind of the wrong ball if you are what i say four pin ten pin reaction meaning he left the ten pin then the four pin which is a four nine but still the four pin that means this is the wrong ball you need to get out of this ball as quickly as possible get yourself something that's going to allow you to have a little bit more room for air and a little bit less a little bit less uh opportunity to leave those
uh corner pins and or the little bit of the high hit that leaves you something you can't make so that is a free tip and some free information right uh conversely speaking if you're not a part of our staff man why don't you get on our staff it's free to join you just go to the website ctdbowling.com click the three little lines a menu pops up click the regional staff it's free you're able to get some insight that we're not showing on youtube uh we actually give the our our staff group some additional insight on these bowling balls especially when it comes to the performance watch down lane
watch down lane so the ball is good but see how that see how it's leaving the four pin i just this is just the wrong piece for this particular environment anyway now you have a little more information about that brand new ball from roto grip and like i said if you're not part of our staff join our staff idle cosmos new piece a lot of hook something that may be useful in the right environment for the right person with that being said on behalf of billy levan i am ceo ronald hickler from creating the difference talk to you soon
[Music] you
Performance Analysis
Performance Analysis
Testing revealed that the Roto Grip Idol Cosmos demonstrates significant hook potential on house shot conditions, with a reactive pearl coverstock that generates notable backend motion. Independent reviewers observed the ball on a standard house pattern using a 10-board, 60-board, 4¾-inch layout with the stock 2000-grit surface preparation. The ball exhibited length through the front end of the lane, which independent testing indicated could present challenges on fresh oil conditions. When thrown with optimal launch angles and reduced axis rotation, the Cosmos produced solid pocket hits and clean strikes; however, steeper launch angles caused the ball to push wide right without adequate recovery, demonstrating that shot execution and positioning play a critical role in this ball’s performance.
On a typical house shot, the Idol Cosmos showed versatility in its ability to adjust to different target lines, particularly when bowlers find the optimal zone where the ball can push into the oil on inside misses while recovering on outside misses. Testing revealed that corner pin leaves (specifically 4-pin and 10-pin combinations) occurred more frequently early in the session, suggesting this ball may not be the ideal first choice on fresh, heavy oil patterns. However, as lane conditions transition and oil breaks down, the Cosmos showed increased promise as a secondary or tertiary piece in a bowler’s arsenal. The ball’s willingness to hook makes it effective in the right circumstance, but independent reviewers noted it requires proper ball selection strategy relative to lane conditions rather than serving as a universal heavy oil solution.
Who Is This Ball For?
The Idol Cosmos is best suited for bowlers who already have a primary heavy oil ball and are seeking a complementary piece for mid-session adjustments on house conditions. Bowlers who understand lane transition patterns and possess shot-making discipline will find this ball more effective than those still developing their fundamentals. This is a ball for intermediate to advanced players who can execute consistent launch angles and recognize when conditions have deteriorated enough to benefit from the Cosmos’s backend motion characteristics.
This ball also works well for bowlers who bowl primarily on house shots rather than challenging sport patterns, and who have the flexibility to adjust their approach based on how the lanes are playing. The Roto Grip Idol Cosmos rewards strategic ball selection and good fundamentals but may frustrate bowlers looking for a workhorse heavy oil piece to use from the opening frames onward.
The Pros
- • Strong hook potential with XtremeTrax Pearl coverstock
- • Clean length through front part of lane
- • Impressive backend motion for heavy oil conditions
The Cons
- • Limited versatility on lighter oil patterns
- • May be too aggressive for average recreational bowlers
