The lowest grit CBN I've used is the 30 micron emulsion. It is very effective on a linen belt. I've been using the same belt for over two years. I don't use it daily but considering I go through three of four 600 grit silicon carbide belts a week it can be cheaper in the long run. The paste form of CBN , which is the product Mark favors IIRC, I haven't tried as yet. The belts can be sourced from Ken Schwartz, along with the compounds, or the Klingspor woodworking shop.
