ok thanks. That explains why I can't find them. I've also noticed if you follow the clicks through to the Lake Country pads, the 5.5" flat pads are strangely omitted. To order them, you have to go to the "pads" area, then click on the first top left link for "Porter Cable and other DA polisher" pads, and then they will be listed.
The ordering "order" of stuff at AGO is strange.
So if I get these closed cell 3" pads, will they behave radically different to the 5.5 CCS and flat pads that are open cell?
