I ride to work on the road while it's still dark outside. Had a few close calls with cars and now I'm starting to think that maybe some light protection would be the way to go. Do any of you guys ride on the road with a spine protector? I'm mainly wondering about a light full faced helmet. I'm wanting more than a standard bike helmet, but I don't want a huge / heavy motocross helmet either. What do you guys use? Any suggestions?
