In my experience, if Smith fits well then Sweet Protection is not going to work. My head measures 60cm circumference, and a Smith Maze fits perfectly right out of the box in size L. Any SP helmet that I have tried on in the indicated size L takes force to even out on, provides an unrelenting vice grip and induces and instant headache.
Interestingly, their apparel seems to subscribe to the polar opposite philosophy of oversizing things dramatically (catering to american obesity trends?) so that I end up swimming in a size L jacket (unlike Oslo, CMP, Otis etc.) Spyder and 2117 also run large but not quite to that extent.
