"I remember lying on the concrete assessing my damage in my mind and thinking 'damn, this helmet is comfortable!'"
interesting; when I had my accident (east-bound, left-turning car where I had a west-bound right-of-way), which knocked me out, I came to with no idea where I was or why, but I was also extremely comfortable! took a while to realize I was lying on a road with my foot in gasoline and an ambulance crew around me. I was in full armour, but my helmet was the worst banged up (SUV in the face'll do that, I guess). Maybe for my next helmet, I'll get what you recommend! I wonder if that comfort is a form of shock?
