current specs.. Left hand, 250 rev, 16.5 off the hand, high axis rotation.

the following is primarily, but not totally, a med-hvy oil and up scenario question.

Several years ago I was told by members on this forum whom I trust that with my style of bowling (low rev, high rotation), I would always want a low RG high differential ball. That did and still does make sense to me since my favorite ball at the time was a storm Special Agent. I've always done well with high diff symmetrical balls, which makes sense. Any ball with a high RG lopes down the lane too long and never gets into a roll. Low differential ball are pretty much the same.

It seems to me that these days the vast majority of balls are higher RG and lower differential, but yet they are advertised as big hook balls, which flies in the face of what my style encounters in real life. The answer is either that they are no longer making the type of ball I prefer (few exceptions) or that the cover stock is so dramatically different that I no longer have the low RG high differential qualification requirement.

I should add that I have had nothing but trouble with asymmetric and will only buy symmetric from now on. I know that there are few balls out there like the Motiv Covert Revolt, but there are many others I would like to try based on their rating to give me some help in the rev department, but I just can't see a .047 or so low rg ball revving enough for me.

Which is true?
Thanks in advance

Differential = flare potential...  which equates to ball motion, so yeah I can understand Ric's assessment on that..

Core differential has a much larger impact than RG ever will, that is and will be my contention...end of discussion
I relate cover stock and core differential to bowlers attributes plus layout with my decisions
These effect how the ball goes through the pins...in my limited experience

+1 .... Core Differential is one of the first things I look at when vewing a ball I might be interested in. High differential balls work great for me as I need flare .... Low differential balls don't ...

Not a shot you Tommy, but I always find it interesting that some people will hang on to piece of information that means little by itself. I know a guy who makes all of his decisions on rg. He'll watch me throw a few shots and say I'll leave a few 4 pins. Instead of adjusting my line or release, he'll suggest I use a ball with a slightly higher rg, even if it's from a different manufacturer with a completely different cover and surface.

If you're a machine or a top 10 pro, maybe you can read the difference between balls with and rg of 2.54 vs. 2.57, but why would you care? There are tons of adjustments I'd consider before rg in and of itself. I know the game has become very equipment driven, but isn't that excessive?

I skimmed over a lot of this and forgive me if it's already been covered, but doesn't the rf and diff. change after a ball is drilled? So unless have the same ball with the same drilling, but somehow with only a slight difference in rg, what are we discussing?

Wow talk abt thick headed and I'm the arrogant one...some get some don't

I thought you were RG...

Tommy, so the whole point was to figure out how to make a Breeze flare like a Crux?  You realize they're not made the same?

Btw my alleged thick headedness (experience) comes from over 30 yrs in the bowling industry studying under the likes of Bill Wasserberger and Ray Edwards as well as being on the PBA tour and forming my opinions off of the results from CATs and numerous situations....if you want to think of me as arrogant or egotistical so be it...I appreciate those that respect my opinions and help

Signed the diff kettle

Thanks for that Mo.

I've since forgot is this in reference to RG or Diff?  The op started on one then went to the other.
