I'm using the Pico X duo for trail running (and loving it!). As I have a kid, most of my running is done during the night and the night is long in the winter season here in Norway
One thing I've noticed is that all lights for trail running are pretty much the same. The light beam is round and distributes the light evenly. But when I run trails I would really wish for a lighthead that gave me kind of an "oval" light, directing more of the light to the front of me and farther ahead, rather than to the sides. I need to look ahead more than I need to look to the sides. Have you, Lupine, looked into this and tried variations in the shape of the lightbeam and if yes, then what were your conclusions?
