I have a bbw/coti on order from srd. I should get it this week. I was looking to use a synthetic progression progression up to 12k, then the coti with water only for the finish. Or should I use the bbw side after the bevel and then finish on the coti? I know grits are in an extremely broad range with naturals. I have read that bbw can be in the 4k range.If so, then bevel, bbw and coti?
