Edit to Previous Faux Pas Post

I failed to mention the pros and cons of full face helmets without or without visors. It's commonly accepted that visor-less helmets are not only unsightly, but are a sure sign that someone's recently taken a major digger.
Well, don't take it from me that full face helmets need to have visors, take it from the UCI's list of 2009 World Cup rules:
"Protections in Downhill/4X:
An approved full-face helmet must be worn properly fastened both when racing and when training on the course. The helmet must be fitted with a visor. Open-face helmets may not be worn."
So there!
