My understanding is that a 30,000 grit stone and green are about the same micron value. Depending on what you use for a substrate for the compound there could be some difference. For myself I use green or gold compound and leather. I keep the strop out and do a mindless strop when I stop to think. I’m interested to see how this goes. I also have some white compound for jewelry work that seems to work about like plain leather, not used much.
