When I started riding, pre-helmet law, in California, I never rode with oneójust wasnít on my radaróalthough I wore some very cool WWI style aviation goggles!
Post-helmet law, when I had a Harley and an old Triumph, I had a half helmet minimal thing. Thanks to good God that my head made it through those years unscathed. When I went back to riding, after many years and wives and children away from it, and went back to my first and best loveóMoto Guzzi, I picked up a Shoei RF1200. I am so used to it now, and itís so light and comfortable, itís a natural part of me when Iím riding, and it would be weird to ride without it. I tried a few Arais and the fit was wrong. The Shoei fits like a glove. YMMV
