Awesome & Light
I picked up the previous model year on clearance (like this is now) so I could get CF for a reasonable price. Although I haven't ridden with the other version I would suspect it's totally worth it. The helmet is so light it is hardly noticeable until you hit a big drop and your neck isn't overcome by the weight. I held it up to a friend's helmet and it was a world of difference. The quick release buckle is a nice touch, all around I'm thrilled with this helmet. I'm about two good whacks in and the helmet has taken each one really well (no damage). One of the few things I've bought I've been so happy with.
