I've now cut with both. One thing I will say, is that I like that Olson blades are not coated with any type of oil. It annoys me to have to clean each one before I use it. I haven't really seen any "this one cuts better than that one", but then again, I'm still new to scrolling in general. I mainly use Olson #5 reverse tooth or #2 reverse tooth. I am going to be starting my first portrait cut soon now that I got some #67 drill bits, and the pin chuck from sloans, so I can do it all on my drill press.
What does everyone do about the oil on the FD blades, and which FD blade do you all use for cutting portraits in 1/4" BB ply.. #2r or #2/0R? I have some #2/0 skip reverse tooth ones. For FD, do you recommend SR or UR blades?
