OLD PO85RD was changed to PO83Q, which has more cut. If this has confused some people...
But yes, PO83Q(old PO85RD) has more cut than PO106FF - and was specifically engineered a few years ago for the introduction of the harder, ceramic clear-coats. They have since then added a more specific array of specialized products, I feel it has not been made absolete, but these products don't necessarily need to be used in conjunction with it.
I use multiple combinations for various situations, but an example being an intact but lightly swirled & ghosting paint on an '06+ Mercedez-Benz.
I apologize, photos unavailable.
PO83Q :: Metabo Rotary, various pads(Mostly orange CCS), speeds & sizes;
PO85U :: Metabo Rotary, various pads(Mostly orange CCS), speeds & sizes;
PO106FF :: FLEX 'RO'; Orange/White CCS
Protection varies. (Irrelevant to topic.)
Overall, I feel that these are one of these best combinations for 'CeramiClear'.
A good reference would be the checks (reference link below) marking "OEM coatings" meaning newer, ceramic clear-coats. Particularly PO83Q & PO106FF.
Note: PO85RD is one of the earlier variants of their ceramic-cut polishes, and I believe it may easily be included, but the above procedure works. As with all Menzerna polishes, combinations are always different depending on the VERY specific circumstances.
