does anyone have a scorpion exo-400 warhawk helmet? i saw it online at this website http://scorpionusa.com/products/exo400_warhawk.html and thought the silver one look pretty cool, but i haven't heard much about that brand. if you guys know anything about it, like comfort, quality or whether its quiet or noisy when riding or anything else, please let me know. i would appreciate any input. thanks guys.
