This is my first post so take it with a grain of salt, but I seriously believe 6D helmets (or at least their design) should be required in professional racing. After recently smacking off a tree racing a Jday, literally bending my handguard to the point where it is up against the clutch mount (cycra probends), breaking my collarbone, and (not doctor checked) almost tearing my LCL and MCL, my head is completely fine. Sure I got a loud crack and my ears were ringing, but I forked over the $500 for a 6D helmet 3 years ago after getting a massive concussion on a DH bike, and can assure you my brain is fine after bouncing off the tree. Having seen James stewarts final crash over and over again, and really missing seeing him at the races, I strongly believe that had he been wearing a 6D helmet, he would still be racing. Just look at how hard some of the 6D riders have smacked their heads off the ground and raced next moto (zach bell for example) I just don't see why we're still allowing full foam helmets to "protect" the pros when basically a concussion proof helmet exists.
