Roto Grip Idol Cosmos
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.

ROTO GRIP KEEPS ON ROLLING
This ball is a good ball for almost any lane conditions, when I first purchased this ball I had my doubts, but it is still used a lot when I need it. When I got this ball it was more expensive, today the price is a good steal and "big bang for the bucks", SNAG IT WHILE YOU CAN. I have dealt many times with bowling.com they won't do you wrong. Ball and company recommended.

Question:
whats the difference between the cosmos and the infinity physix ?
Have an answer to this question?
Answer:
The cosmos I believe has the xtremetrax pearl and the infinite physix has the REX pearl cover stock, both sanded to 4000 grit abralon, the physix is meant to turn the corner harder than the cosmos due to the asymmetric core.

Question:
I have the Zen Pearl. my favorite ball .. I will also be getting the Wolverine Dark Moss. Is the room in my bag for the Cosmos ?
Have an answer to this question?
Answer:
The Idol Cosmos will give you a slightly earlier read on the lanes compared to the Zen Pearl but it is stronger than the Wolverine Dark Moss. I am not sure this really works as a ball to use in between the Zen Pearl or Wolverine Dark Moss but it would give you a slightly different read than the Zen Pearl if you just needed another option for medium to heavy oil that maybe did not break quite as late. I think the Zen Pearl and Wolverine Dark Moss are a great 1-2 punch though.

Question:
What is the difference between this bowling ball and the Storm Axiom Pearl?
Have an answer to this question?
Answer:
They are going to be very comparable. Both are upper mid performance balls and both are designed to work in medium to heavy oil lane conditions. Also both have a hybrid coverstock but the Cosmos may have just slightly higher hook potential due to the finish being a little earlier and and flare potential a little stronger.

Question:
Is this ball similar to the idol pearl
Have an answer to this question?
Answer:
This is very similar to the Idol Pearl. They have the same weight block but the Cosmos has a different pearl cover and a 4000 grit finish which reads a little earlier than the Idol Pearl that had the polished finish out of the box.

Difference between defender solid and cosmos
Have an answer to this question?

Hi! The solid coverstock high performance Brunswick Defender Solid would react earlier and more aggressive than the pearl coverstock upper-mid performance Roto Grip Idol Cosmos.
