Ok, since I don't want to get anyone's panties in a bunch (i.e. the "Do a search" zealots...), I'll end it here (since I started this thread).
To those who actually engaged in a *logical* discussion as to what could possibly be better (in terms of *safety*) about 2 differently priced helmets which are *both* Snell and DOT certified, THANK YOU. To those who *still* resort to the very lame (sorry, that's what it is) "If you have a $200 dollar head, buy a $200 helmet. I'm going for the $400 helmet...), you ENTIRELY missed the point. Frankly, I think my head is worth *more* than 400 bucks, or a thousand, or even a hundred thousand bucks. I really enjoy life, and I value mine. But guess what - buying a more expensive helmet (because it simply has better *ventilation*) doesn't necessarily mean you or I are actually getting better protection.
Special thanks to dj dunzie (who actually made a reference to *scientific evidence* in the form of a written test article). It's refreshing to know that some people here actually take the time to read what we all write.
