sweetlou- Dunno how helpful the following will be to you, but maybe something will be of value.
I never do well using large pads for correction on machines like this. 5.5" is absolutely as big as I'd go (and I really prefer 4" for serious correction).
IME the *small* (i.e., 3.5-4") PFW pads can work well with this type of machine, but I *think* the 6.5" will be too big. Unless you're gonna run small pads with a little backing plate, I think you might oughta stick with 5.5" foam instead.
For cutting, I'm hard-pressed to say whether you'd be better off with yellow or orange :nixweiss Most people use orange these days, but sometimes, if you have hard clear, the yellow is a better choice (even if it does leave more micromarring). Sometimes you even need *both*, first the yellow and then the orange, but that's pretty rare IME.
The differences in finishing pads always leave me :think: too. Once a pad is gentle enough to *NOT* impart any cut of its own, any differences seem to be a matter of firmness and porosity. Some people like a certain "feel" to their pads and some pads just work better with certain products. But it's not like most people *need* all those difference choices. As I understand it:
-The blue would be for final polishing or using an AIO
-The black/gray is sorta along the same lines but even more gentle and also better suited to LSPs
-The red is an LSP application pad that's even softer (does this matter? In many cases I doubt it; use whichever *you* like).
-The gold pad is supposedly *VERY* good for light/thin LSPs like sealants; it doesn't soak them up the way most foam pads can.
In *most* cases I'd only use the blue pad for burnishing/jeweling and/or maybe AIOs. I don't much care for the black/gray pad and never seem to use mine- it's not quite open/porous enough for use with AIOs and polishes IME and that can lead to loading/caking of product. If the red wax pad from Griot's is the same as this, then OK...I really like that red Griot's pad but I dunno if they're really the same thing. The gold pad sounds great for use with liquid LSPs. But the preceding is just how *I* feel about these pads and others might have completely different opinions.
So your plan of orange (or yellow), white, and red sounds good to me but I'd pass on the 6.5" PFW.
