Another thing: how has everyone been doing the initial flattening (I know about the final smoothing) for these? I don't have a D8XX & don't really want to buy one for just one stone. Has anyone used (good) wet/dry paper @ the 120 or so level? I can then go to my D8C & then onward, but I'm wondering about scratches from bad paper for the 1st step in the process.
