I love the flip down visor too BUT...
I sometimes just use that on real hot days and leave the main shield up.
This, I found, is like an open invitation to bees to be scooped into the helmet and only get pissed off when they hit the flip down sun screen and then crawl around for a while 'till they find your neck, right under your ear so they can sting a real soft spot.
Ask me how I figured THAT out!:tsk:
bastards!
