Anybody wear a Leatt Brace? They are pretty popular in motocross at DH biking. Could be a pretty useful when doing inverts. In case anyone doesn't know what a Leatt brace is, it's a brace that pretty much eliminates any possibility of breaking your neck. They are expensive though, like 400$. Thoughts?
