Go 3/4 helmet, best of both worlds. I bought one earlier this year and love it. Just got back from an 800 mile trip, mostly on the interstate on day one. Cold, windy, I stopped and popped on my clear shield. Much better. Day two, sunny and warm, visor went back on vents open. Best thing I've bought from my bike. Did this trip last year with a 1/2 helmet (DOT). What a mistake, so unbalanced. Once you go 3/4, you can't go back to half.
I have the Scorpion EX0-200, but most major manufacturers seem to have some type of 3/4 helmt. Bought mine at helmet city, added dark visor as well.
