I think I have about six helmets around here. I just bought the HJC FS
-2 from Ebay for $49.99. This is a half helmet with an air scoop on the top for that ram air cooling. I have the Scorpion Half Helmet that has the intergraded slide up face shield. I never used the face sheild and it was not vented. I also have the Nolan Full-face if and when it may get cold here in South Florida. I like the FS-2. It;s light, and good ventilation.
