Noting that I haven't used the blue pads in question...
Just because there are lot of different grades of pads, that doesn't mean that you *need* to use them all. It's a matter of how the pads behave on the paint in question and sometimes there aren't any appreciable *functional* differences between various pads.
For years the only pads for the Cyclo were the green ones and Griot's orange pads were all he sold for a long time too (worked OK for both polishing and waxing).
FWIW, I really like the Cyclo white pads for final polishing and LSP application. Unless a paint is *VERY* soft I can't see needing anything softer than the white pads (they work fine on the Jag's soft ss lacquer).
If somebody prefers the blue pads, I can understand it; hey, personal preference. But it's not like we all need every type of pad to get a good finish.
