On a more serious note than before, I'd wait until the rules all settle down before buying anything specifically for Enduros.
Over here the current rules tend to be that a helmet must be worn at all times, including transition stages. Which is a (understandable) pain in the @rse as I'd often like to have the fullfacer for stages, but screw climbing 4,500ft wearing it! And Euro style with fullfacers required on stages is a pain too as you'll really want to carry an XC lid for the transitions.
Quite how this'll change now that the UCI have their hands on the rule book, nobody knows

In the Whistler derp, I saw quite a few riders coming down the mountain with full face helmets on their heads and XC lids strapped to their backs.
