No worries about taking a while to reply — it was worth the wait :)

It doesn't seem to be enormously easy to find hard data on these helmets; all I could find was a press release stating that Hövding helmets can reduce acceleration to 65g, as opposed to the 250g standard. I know very little about this, but 65g still seems a lot to me! What do you think the standard should be? Or is this the wrong way of testing it?
