How do you know which pad and polish combination is more aggressive than the other if they both accomplish the same job. For example, is Menzerna SF4000 with and orange pad more aggressive than Menzerna PF2500 and a white pad?
 
My thought on the subject is:

Both combinations may be similar in terms of agressiveness but are not exactly the same. One would be more agressive than the other, possibly only by a matter of degrees. If that is true and both are able to do the job of removing swirls and other imperfections then one of the combinations is more than was required. However, my belief is that dialing in the least agressive combination is a somewhat inexact science (unless you're Mike Phillips ;-)). You do the best you can.
 
•Don't forget to also figure into an aggressiveness-equation:
-"Type" of buffing machine
-Arm Speed
-Down force/Pressure
-Pad size
-Amount of product on pad:
(up to and including pad saturation)
-Panel temperature
-etc.

This type of question has too many variables to answer. Some have done odd pad and polish combinations (like using a finishing polish with a cutting pad) with unique results.

IMHO, it's easier to try to go with a pad/polish combination that is somewhat matched on normal paint (paint that is not impossible to finish down on). So, I would use something like SF 4000 with a white polishing pad and PF 2500 with an orange cutting pad as needed.

While trying a myriad of combos may be enjoyable for some, I'm just looking for the easiest tried and true method to get the job done. This is why I'll reach for the Rupes system most of the time.
