I read the whole thing and it was so back and forth and seemed not to make clear decision on any certain thing. Almost like a politician wrote it. Softer shells for were better than the harder shells for lower impacts and but harder where better for catastrophic wrecks. I am still on the fence as to what helmet would be better. I mean you go buy a $400 helmet and have a small speed get off, and you are worse off than having a Tractor supply helmet. I know that you can have one with Kevlar and all that jazz but the minute you drop it it is toast and as far as I can tell the lower cost ones are rated still at 300g's and that it still holding up to way better than that of a 80g hit that of two monster line backers colliding at full speed on a football field.
