mongo- IIRC, I used speed 4.5. I've used both Griot's orange pads (similar to LC tangerine, very different from "normal" orange pads) and a finishing pad. I generally like pads that are more "open" or porous than finishing pads while still not having any cut in-and-of themselves when I'm using AIOs (and the Griot's pad is a good example), but that's just me.
