After a 45 mile ride in to work the other day with the sun in my eyes and excessive noise from my X1 open face helmet, I took the plunge and ordered an LS2 OF569 from Amazon.

First off, it matches my Vespa GT200 very nicely. I love the flip down sunscreen, fit of a medium matches my other helmets, and the quick clip (as opposed to D rings) is super nice. It's also super lightweight. If only it fit in the old pet carrier, but luckily it still fits in my small top case I have.
I'll update when I've taken her out on the highway regarding noise, but as of right now...this seems like a great bargain of a helmet.
