I find it entertaining when people try to prove me wrong. Sometimes they do, and I chill. But now it aint gon happen
I highly doubt anyone's head is only a perfect fit for only one helmet, and that one happening to be a 30 quid one. |

Hmm,
Interesting dicussion. However ECE regs are not nearly as good as old BS type A or american snell standard.
ECE test helmets in a number of places and measures deceleration but only hit the helmet once in the same place.
Snell to 2 drops on each point. Arai do a lot more drops at the same points and far exceeds current regs. They feel that often you have multible impacts in a crash so its important the lid keeps protecting your head.
Point being there are some very cheap chinese lids coming over from the far east that will just pass the ECE regs but only just, and some good quality lids that will way exceed ece regs.
Another interesting point raised in last weeks MCN and superbike magazine is ACU Gold stickers. Its an absoulute discrace. Most lids are not even tested by the ACU. If they meet ECE standards and the manufacture want to get ACU gold stickers they buy them for a few quid each.
MCN pretended to be an importer of some cheap chinese lids, made up a fake name for the lids applied to ACU and ordered 3000 stickers to be received to the bike show. All they did was send a photo of the lid. No tests.
So ACU gold sticker at the moment means naf all. Its just marketing. The head of ACU did coment that they are working at doing something like the Ncap car safety ratings where lids get a rating for safety. Now that sounds like a great idea and will encourage manufactures to make safer lids.
My advice for what its worth is as others say, get a lid that fits proberly and stick with a reputable make-eg HJC, Nolan, X-Lite, Nitro, Shark, Roof, Shoei, Arai etc.
Sorry for long possibly borring post.

Something which I find very important and which definately DOES vary between brands is the noise insulation.
Saves you wearing those ever-so painful earplugs on those 1000mile days.

The Snell test is too harsh in reality, making the helmet firmer than it needs to be, to survive the damage from a double impact in the same location.
In real world accidents, the incidence of an impact from the same sized object in the same location, with the same force is so unlikely it can be discounted. As a result, the Snell test requires the internal foam of the lid to decompress less, given the thickness avaialble to it, to account for the infinitesimally small chance that you will hit the same object again, in the same bit of the helmet. this means the head is subjected to a greater G-force than is actually required, and doesn't actually Help.
By utlising the full thickness of the foam, Non snell conforming lids (but which meet all other standards) subject the head to lower g-forces, and as such, are actually 'safer'
more info here:
https://www.motorcyclistonline.com/gearbox/motorcycle_helmet_review/
| Quote: | Dr. Jim Newman, an actual rocket scientist and highly respected head-impact expert—he was once a Snell Foundation director—puts it this way: "If you want to create a realistic helmet standard, you don't go bashing helmets onto hemispherical steel balls. And you certainly don't do it twice. |

That's quite interesting.
It made me ponder whether helmets for bike use and car use should actually be designed differently - as you fly over the handlebars and tumble along the ground there's a very small chance you hit the same bit of your lid repeatedly in the same place (real impact, not just scuffing along the ground).
But if you're tightly harnessed into a racing car, I'm thinking there's a reasonable chance that you dunt your head repeatedly off the same bit of roll cage as you perform a quadruple barrel roll into the kitty litter.
