Hello Diane,
I have been scrolling now for a long time and for any sort of fine work (I mainly do fret work - as opposed to portraits) I always use the Olson blades. For fine work on timber of less than 6mm I use the # 2/0 skip tooth reverse. Timber thicker than that I will probably go up the #2, skip tooth rev. Reverse blades are a must....they reduce sanding to practically zero. The Olsons are not as aggresive as a lot of others and give you more time to think, plus they turn a lot better, I find. I don't think I have ever had a better finish than with with the skip tooth rev.
For more "open" work I use the F/D ultra reverse. They are an exceptional blade as well.
But having said this, blades are a very personal thing - nearly everyone has their own preference.
Hope this helps
Noel
