Yes. Wearing a full face gives me a lot more confidence when hitting bigger & newer things. Just the feeling that my face can't be smashed in, body armour is awesome too, i mean, with a full face + body armour + shinnies, what's the worst that can go wrong!?
though that's on bigger things on a DH track, you'll probably get bagged shitless if you wear armour on DJ's. You should always wear a full face if you're not 100% sure you'll clear it easily though.
Have you ever done this, got close enough where you can't back out ... and slammed on the brakes? Where it was the worst possible thing to do and you know you shouldn't have done it, but you did anyway! Maybe it's just me
I know i have anyway!
