Hey Boss, It's not the cover stock hardness, it's the hardness of the particle they add to the cover stock! Just like the hardness of the cores and what they put inside of them have changed. Lane Masters told me before they went out of business that changed to the carbon particle to try to match the diamond particle as close as possible. Just my $.02, Bruce
From USBC website:
Material
1. The ball shall be constructed of solid material i.e., no liquids and without voids in its interior.
2. Any material added to or included in the coverstock shall be equally distributed throughout the
entire coverstock of the ball, except for materials used in logos and other required markings.
3. The density of any piece/component in a ball (e.g. core, coverstock, weight block, etc.) shall
not exceed 3.80 g/mL (i.e., no pure metals or high density materials).
4. Following approval of the ball, the introduction of substances that are not comparable to the
original material used in manufacturing of a bowling ball is prohibited. Likewise, altering a
bowling ball in any way so as to increase its weight or cause it to be off balance outside the
specifications is prohibited.

I can't find the video on bowl.com anymore, but they showed portions of the ball approval process and there is one test for particle hardness that utilizes a curved glass plate.  They hold the glass plate against the ball while it is on the spinner and if the glass plate is scratched then the ball isn't approved since the particles are too hard.

OK I understand the hardness of the particles now. Thanks for clearing that up. So I guess the NS and YB is grandfathered in but can not be manufactured under today's USBC standards.

Another question. What was the reason that USBC gave for prohibiting the diamond particles?

I would presume it had something to do with reducing or eliminating lane wear... after all, if it scratches glass, it's going to do more than blow the pattern apart. 

On edit - found the video.  Particle hardness test is at the 5:07 mark http://www.youtube.com/v/J2wKCSRw3WA&hl=en&fs=1&

Looked like L/M found the best friction additive possible and then was prohibited from using it in future balls. Am I correct I saying that the only L/M balls that have the Diamond Particle cover are the New Standard , the New Standard 2, the Yeah Baby, and the Big Kahuna? And I guess that is why the New Standard Limited was not approved. It has the exact same specs as the NS and is on the non-conforming list.

J_Mac thanks for the video, Never seen that one.

But somehow, the Carbon particles were approved by the USBC and used in many other balls, like the original Big Bang, and they were barely "softer" than the diamond dust used in the Legend series. I learned that from Johnnie Jones, one the original owners of LaneMasters.

Question - Is the New Standard legal to use in a Tournament...

Of course. It's been approved a long time ago. They don't withdraw approvals.

They can change the specs for new balls, but they don't change them retroactively.
The Ebonite Vortex II, the original V2 solid, has an RG that is too low, 2,45, by current standards, but if you have one, it is still legal to use because it has already been approved. The same is true for the Visionary Centaur AMB Solid, whose RG Differential is .062", which is over the current standard of .060". It has been approved and is still legal. If you use it to throw an honor score, that score will be approved, because the ball is still approved.

I use an Immortal Pearl with a .78 Differental and that was BEFORE I drilled it. I have NO idea what it has with holes in it. don

Used it for the 1st time a complete 3 games..

This ball does change the pattern on the lanes... It will change the pattern and create a path and will turn when it hit friction..

Thanks for the help ...
