Hey guys, I'm looking into buying a new helmet and am really interested in the Lazer O2. As I've read on the forum, it's a great helmet. But in one review I read, it said that the fit is odd with bigger heads. I have a pretty large head (don't have a size-estimate since my current helmet is a Giro Transfer which is unisize) so I was wondering if some of the larger-noggin individuals could chime in?

If it helps at all, I faintly remember a medium Specialized Echelon being extremely uncomfortably tight on my head.

Thanks for the help.
