Boo boo bandaid is really great. Well played.
Coming from DH and mainly doing the Trail riding (Enduro, gravity, enduro, all-mountain, cross country whatever it's called) thing, I often wonder if it is any safer at all.
Riding smaller bikes, often tighter trails and usually as fast as possible does not equal safer. Full face could be justified but unless i was the one with the humorous bandaid on my face, I don't think I would ever stap the full face on for a few hours on the trails.
Heal well, and hope you find your new nose suitable.
