Is a medium oil ball a good choice for dry or oily conditions?

[NewToBowling]

Here are a couple of Simple RG scales (there are others, it depends on who you ask. There's no one set scale.):
Low RG: 2.460" - 2.570"
Med. RG: 2.570" - 2.680"
High RG: 2.680" - 2.800"

Here's another:
Low RG = 2.430 to 2.540
Med RG = 2.541 to 2.690
High RG = 2.691 to 2.80

Simple Differential scale (there are others):
Low Diff.-RG: .01 - .02 (low flare potential)
Med. Diff.-RG: .021 - .04 (med flare Potential)
High Diff.-RG: .041 - .08 (high flare potential)

I've seen those scales and that is what brought up my question. Going by those most balls are low RG as I don't see many if any over 2.57 (someone correct me if I'm wrong)

In away your right, most balls out are lower RG. Hook sells, people don't want balls that go longer cause their perceived as weak.

So there are fewer actual high RG balls, so you have to hunt for them.

If you go by this scale (BTM's)

Low RG = 2.430 to 2.540
Med RG = 2.541 to 2.690
High RG = 2.691 to 2.80

Most balls out range from low to med. RG which is more accurate I think.

It looks as if my suggestion has brought out interesting information. In watching the review of the Ultimate Nirvana, the layouts override quite a bit of the hype.

The Ridiculous Asym by Radical would meet the criteria as laid down.

Jab.... I'm more old school lol my old neighbor was Sir mix a lot....ill be playing "Posey on Broadway" on my way to bowl...hehehe

I'm more of a surface, high RG, symmetrical (more forgiving, controllable) guy.. With asymm cores, they are great at playing away from the pocket (inside) for 325 rev rate guy like me. BUT, surface is much more important for me.

I don't concern myself too much with layouts. I have 3 layouts I use for flare management, but surface prep again takes precedence.

Fantastic link, 1820. Thanks for posting.

RG discussions always stir up a lot of varying opinions for the simple reason that very few bowlers really understand the effect that the low RG measurements have on bowling balls. Friction is easy to understand, but the resistance created by the Radius of Gyration is harder to grasp. While the measurements seem very close, they do make quite a difference, especially for lower speed, lower rev players. For my part as a bowling writer for over ten years, I consider the RG ranges to be: Low (2.47-2.51), Medium (2.52-2.55), High (2.56+). While 2.58 is usually the highest RG that we have seen for "serious" bowling balls, the new Storm Fight with a low RG of 2.62 at 15# could be the portent of a new trend.

Rob, didn't you mean that 2.62 RG is HIGH? The 0.043 differential seems to place it in medium.

Thanks for your clarification. Your numbers seem more inline with modern balls

Every bowling ball has 2 RG's; a high RG and a Low RG. The high RG is often not listed as it is simply the difference between the high RG and the low RG that is the differential. 2.62 is very high for a low RG. For example, a ball with a low RG of 2.50 and a differential of 0.050 has a high RG of 2.55.
