Types sanding disks: Brilliant 2, Cristal, etc. Help!

[hobkirk]

]I have 4 boxes of Festool discs plus a few other discs for my 150/3 ROS:

• Box Brilliant 2 P40
• Box Brilliant 2 P80
• Box Brilliant 2 P120
• Box Brilliant 2 P180
• 3 Discs of Brilliant 2 P220
• 3 Discs of Brilliant 2 P400
• 2 Discs of Cristal P60
• 1 Discs of Rubin P80
• 3 Discs of Rubin P120
• 3 Discs unknown name, very coarse (at least 36?), 1 dark maroon, 2 black - maybe not Festool, the holes are perfect, but I have no recall where I got them.
• 1 disc labeled S2000 (I assume this is Platin).

[list type=decimal][*]Is Brilliant 2 equivalent to Granat? or Granat Net?
[*]What is Cristal?
[*]Is there any real advantage to Rubin over Brilliant 2? I plan to toss them in the corresponding Brilliant 2 boxes and grab them when sanding pure wood. Sensible?
[*]Was there probably a sample pack included with my ROS?
[*]Any suggestions to identify the ultra coarse discs?[/list]

Thanks you, patient reader.

The dark maroon super coarse is Saphir.

- Brilliant is now discontinued, but was for bare wood and finishes. Granat is more of a general purpose abrasive for just about any type of application.
- Cristal is now discontinued by Festool. No longer available.
- Rubin is made for bare wood. Brilliant is also now discontinued, but was for bare wood and finishes.
- Festool used to include a small sample pack of abrasives prior to about 2014. They now include only a single sheet.
- The back of the abrasives have the grit and abrasive series (rubin, granat, etc)

More info on the Cristal.... This was a resistant-to-clogging Abrasive that predated Granat and tends to leave a different scratch pattern than either Brilliant 2 or Granat, but is still a great abrasive on its own.  I think personally, it won't hold as long as a disc of same grit Granat in use for shear cutting ability, but if you've got it, use it up, no point going to waste.  It was also cheaper than Granat if I remember right. 
So, old paint , old finishes, or even bare wood, have at it.

I have used Rubin interchangeably with Granat for bare wood but mostly in grits 120 and below. I like Granat better and feel it lasts longer than Rubin but there is no reason it can’t be used just like Granat based on my experience. Don’t know about the other types.
