Ive contemplated my Mx Lid while boarding with some of my crazier friends. I have my ski lid that I wont ride without (CA, Sierra Cement). But for the hikes and Drops having my full face lid has crossed my mind (thought the added weight on the hike also crossed the mind). I use it when I go downhill MTB'n though. 50mph with a simple bike helmet doesnt feel safe and its nice to have my goggles to keep the dust out.

Here is an interesting article, although it's about football helmets:

NFL, manufacturers agree there's no perfect helmet - Yahoo! News

The best thing you can do is have a full face helmet of any type.

I found the SHARP website. It says nothing about how helmets are tested or how the ratings should be interpreted. I have no confidence in a ratings system that the rater doesn't define. ESPECIALLY when it comes from a government.

What does "70%"; mean? Who said it? How did they arrive at it?

I found £250 helmets from 2-star to 5-star. I found a 5-star at £170 and a 2-star for £450. Is there any correlation at all between rating and price?

Buy a DOT-certified full-face helmet that fits you well and has comfort and convenience features you like. Make sure you get one shaped for your head. I once bought a very expensive helmet that just sucked because it gave me a headache after wearing it for an hour. I really like an easy-to-remove faceshield. I like a removable liner for easy cleaning. And plenty of ventilation that's easy to operate even with winter gloves.
