I have spoken more than once with Galen on this subject, and although I always  recommend an email or call to him when people have questions, I know that all of those that you listed have a "grit finish" of 800 gray scotchbrite, as well as a coat of polish if that is what the ball is OOB when you get it.
 The sequence to get them there, as well as a link with ball descriptions (page 11 of 12) are below:

1- 400 wet sand
2- 800 wet sand
3- 800 gray scotchbrite pad
4- coat of Factory Finish polish (for the resin part of the cover)
5- again, 800 wet sand
6- again, 800 gray pad (steps 5 & 6 are used to "raise" the particles)
7- then, a coat of Legends "FF" polish (WCR, MP, Terminator)
* The SHEEN finish for the others is accomplished when step 6 is completed *

Any questions
