Definitely use the optimal setting for less sanding. But you will have to do some sanding most likely. I used to hope to avoid it but have quickly found out, like others, that it's just going to be something you must submit to. I have found that using a variety of techniques will clean up a project nicely. Generally I start with a large sanding mop attached to my Makita drill. I'll then move onto a Demel with a variety of carving bits and radial sanding discs.

I think the theme is becoming clear that using a hardwood will "generally" yield the best results over using a softwood.
