Depending on my tool control that day a small spindle of cocobolo, dogwood, or ebony I might only use 800 paper or so.
I got used to polishing the cutting edge of my spindle gouges on the Tormek water wheel - a razor-sharp mirrored edge is a dream to use, just like with carving tools. Bigger things with coarser wood: the grinding grit doesn't make much difference.
I put a 600 grit CBN on the Tormek and while I like it, it doesn't give me the edge I got with the water wheel. I may try the 1000 grit.

John, I would agree with dense woods like exotics that a polished edge would make a better cut than without a polished edge. My frame of reference in my comment was basically turning bowls, but you certainly make a valid and a good point here. Especially with the skew, detail gouges and working spindles out of exotics which are dense. Finials are a classic example of this.
