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

Focus first and foremost on cover strength then reference differential...RG is minuscule when you are talking thousands of an inch in dynamics

I am more in the Ric camp.  It seems to me when I bowl league that about 75% of the bowlers have the wrong surface prep on their equipment.  Too many rely on OOB to be the end-all be-all for their game. 

I think in reality you will want drilled dynamics to be on the strong side and adjust the cover prep for the length of oil you are encountering.  During my wife's prep for the US Open, we changed the surface during the practice session until the ball rolled out then moved up from there.

Thanks for the replies, but we're going in the wrong direction from the original question... I know all the mantras, truisms, all balls are asymmetric, Rgs can be jacked around...yes, yes, yes... Apologies if I wasn't clear as to intent of the question. Let me rephrase the question to a scenario we've all heard before...

Question is really if today's coverstocks will allow a low rev player to ignore the natural tendency of a higher Rg ball, which will not rev as easily, to be considered a viable prospect for those of us who need the extra help to compete on slicker conditions. Let's go to our friend the snow tire... A fast revving snow tire will not push a car through ice if it cannot grip. Add studs, and it will begin to push thru even with a slower revving tire. Add more studs or longer studs, and it will push thru even better. This would create a condition where even a slow spinning tire could push thru the snow better than a quickly spinning one.
3-4 years ago, you would rarely see a heavy oiler with higher Rg and lower differential because you still needed the faster revving engine. If your hand didn't provide the revs, the core had to help. Higher diff provides higher potential...  During those times, you would not see balls at .040 or lower diff claiming to be an oiler. Today, there are quite a few more balls claiming to push thru snow with slow revving engines...  Heck, we even see UNHEARD of diffs that begin at .02x and .03x claiming to have a backend on medium to heavy conditions. Surface prep is important, but only a part of the answer, and 3-4 years ago surface wouldn't fix the problem, therefore the balls and the claims weren't being made. Why now? Are the coverstocks that much better?
Thanks

Surface finishes today compared to a several years ago is the biggest difference.

The difference between a diff of .030 and .040 is .01 which is measured in the hundredths… .and yes can greatly increase just from drilling.

Things that hurt bowlers most are putting drill sheets in the box and posting core information. What the manufactures intent for the ball already factors in the core,  cover ect. The goal is to match that with the bowler and the condition they are going to be bowling on.

A ball with a diff of .030 retains energy and even in heavier oil with the right surface can create downlane motion.  No matter the core specs it's the surface along with the layout that you want to focus on when matching up to the conditions.

I appreciate all the expertise, but frankly, I side with those on the board who have all said frequently that although it may not seem to matter, it clearly does when we see the evidence of our own eyes. Evidence must be examined, not thrown aside, and I've seen Rg matter too often to deny my own experience.
Oh good grief, I give up. Why do I even post here... ?  Sigh...

For me it's both, surface and Rg that have the biggest effect on ball motion.
I have several balls that are in the higher Rg range. They all have different cores and coverstocks. I have a high-speed-to rev release. All of these balls tend to go way too long when compared to my lower Rg balls. For this reason, I fare better using low Rg
equipment and simply adjust the surfaces when necessary.

5 Star thread ! ! !  BR gold.

My 900 Global Breakdown is a prime example of this.

For me it has been the Ringer line, and the LT48. Wow very unexpected results. My ball choices are usually only limited by color, and terrible logos....the rest Im not worried about.
