The scales on my BGSFNO (SFNOBG?) are micarta, and the pins are not set so deep as to be uncomfortable to me. Although I haven't done anything more with it yet than play with the balance; that will come later, just not enough time to get out yet this spring. They are pretty thick scales, IMO, but not as contoured as, say, the BGTG and TG-M (which are pretty much the same contour, both G10). I wish the scales on the BGSFNO were slightly more contoured, as that would help with the grip while choked back on the handle for chopping.
If I could have the BGSFNO in the same thickness as the TG-M (which is 0.22), with slightly more contoured scales, the knife would be almost perfect. Change it to INFI, and it would be pure perfection.
