I'm in the same boat as you Noodle man!
I've tried on a few helmets so far: Salomon, RED, Boeri, and Giro. I've liked the Giro G10 MX the best, but it still feels a little loose on my head (tried on the Medium and Small...med is close to being just right, small is too small).
The other brands I've tried on have felt weird. I seem to recall reading a post either here or on TGR describing that some helmets are designed for round heads and some for oval heads. I'm pretty sure I'm not liking the rounder ones (I think they were Boeri and RED, if I remember how they felt).
I'm still actually looking for a good shop in the area that has a really, really extensive selection.
My buddy, on the other hand, just wears his motocross motorcylcle helmet.
I JUST NOTICED THE "CAM" PORTION OF YOUR HEADER.
Didn't mean to hi-jack, just missed that important detail.
That said, if you have any helmet rec's...
