Me, I dont got much in thu hemmet I gotta pertect, so i just gets thu cheepes une i kin find.
I look at terrain & speeds on a dh bike & sled in comparison... DH is WAY more dangerous. Whatever the testing, if it can protect me on my bike where I crash into large rocks about 20+ times a year, it'll do on my sled where I MAYBE take a couple good hits to the head a year (yeah, I've taken quite a few in the ligther helmets & not a single issue yet)
On the other hand, I DO buy a new one each year, with the amount of crashes I take on my bike, I like to have a new lid each year.
I've got a couple really sweet, near mint DH helmets for sale...:face-icon-small-hap (make you a killer deal!!)
