it makes some interesting reading.

Thanks for this - fascinating.
Word of caution, though...there's a HUGE row about the Sharp testing, as to whether it's worth squat or not.
Now you might think that Arai, for example, who can charge you £600 for a lid would cry foul when beaten for safety by lids costing £80, and fair enough.
But it's also worth thinking that however much people pay for the name when they buy an Arai or Shoei etc, what's thing actually made of, how much research has gone in to the build, does the company actually have a test facility (don't laugh, HJC's cost $6.4m to build when they decided to sponsor Ben Spies are luanch top end stuff). Point is those top end lids are engineered to be as good as possible. Whether they're worth £600 is a different question. They're not churned out to be cheap, whereas your Box effort is.
How many of Sharp's high-rated low price lids would get an ACU Gold Sticker? None. So are ACU idiots, or are they testing different things?
I'm not saying either side is right, but it'll take quite a lot for me to stick my head in a budget lid on the say-so of a bunch of civil servants....
