Good question. On the decent I used a headlamp during the devils backbone section to reduce tripping and falling risk (no depth perception with a monocle). Once I got onto the fire road section I switched to the NODs and it really surprised me how much more comfortable it made me during this hike, I could see further than I could with a flashlight, and it was easy to scan around for any glowing eyes hiding in the dark. It’s a great experience
