I think the classic Buck fixed blades are beautiful looking.
I very much prefer a folding knife for backpacking, mostly due to weight but also for ease of carrying. The Buck Bantam and Spitfire are both in the 3.5 oz range. My preferred backpacking folder is bigger than a 110 and weighs only 2.5 oz - no sheath needed and can be pocket carried without interfering with my pack's hip belt.
This said, I do wish Buck made 100 series fixed blade more oriented towards backpackers. I would like to see the old (very old) style sabre grind, as I find it much better for wood working and generally tougher and more versatile than hollow grinds. Hollow grinds are my preference for hunting knives, but not general woods use. I also like something more of a drop point or modified (straight) clip point blade.
The Selkirk's blade shape looks right to me but it lacks the BOS heat treatment and I prefer the classic black phenolic look. The Selkirk converted to a US made 100 series knifes would be very, very interesting to me.
