find yourself a helmet that fits you correctly FIRST. then start looking at what is available in that helmet. once you find a helmet that fits you correctly, let me know.
just a note on these "low priced" top of the line helmets. a good bit of them are much cheaper than you can buy new, but you give up time when you buy them. if the helmet you buy is $450 and it has been on a shelf for 2 years, you only have 3 years of life left in that helmet. that comes out to $150 per year for that helmet. that means you can pay up to $750 for a brand new helmet with no time on it (5 years @ $150 per year) and be in the same spot. just something to think about.
Being right is bitter-sweet when you're ruled and surrounded by morons.
