Just wanted to ask those who have experience with the DMT slurry cards, which grit they prefer to use. I've had the green one ( extra fine ) for some time now, and as you can see by my pic, I've worn it out. I've been using it on my Coticules, an unkown slate around 5-6k-ish, and my Zulu grey. Just wondering if one of the other grits might be better suited for what I'm doing. Seems maybe the green is a bit too fine.
