I am still looking for that elusive perfect fitting, lightweight, less noise, great ventilation helmet! I have one now that meets a few of those criteria (Exo 400), but I'd love to walk into an MC shop and have an Arai guy, for example, fit me by finding the right helmet for my shape head, then try on carious size pads to get to the right fit. I'd buy it no matter what the price (well, within reason).
I also read a lot of reviews and see a lot of helmets that would work online, but other than the usual four of five brands EVERY shop has, it is next to impossible to try on that one helmet that sounds great!!!
