i ride with mine up at night. its not worth not being able to see down the road, especially with the amount of wildlife here in upstate new york. i don't mind the bugs in my face if it will save my life.
I carry an extra face shield when I ride the street but every once in awhile I don't but I carry a pair of cheap safety glasses under the seat so if i do have to flip the visor I have the eye protection.
that looks good...but i would really be concerned about comfort.
i hate riding with my dark shield at night...but sometimes it happens. on residential and slow speed (like below 30), i just keep it up, with no eye protection. above that speed, i just ride with it down
i think it looks pretty badass pulling into a parking lot with a dark shield.. lol
