I have 3 helmets and here is my opinion:
Bell Apex - Good helmet with great stability and venting. $80
Scorpion EXO700 - Best comfort and lining. Best anti-fog on the standard face shield. $100
HJC AC-11 - Good helmet with good comfort. Poor poor stability and noise, but is now an outdated design, and I expect the newer HJC's are better. Runs a little looser than the others. $60
The Bell is my preferred helmet due to what I need, but the Scorpion is a very close second. I like the HJC also, but do not use it much any more. Depending on the weather conditions and which windshield is on my bike effects which helmet I use.
I know, I bought the low priced helmets when I found good deals. I did try on some other more expensive helmets, but am very happy with these, and I think going to a $300 or more helmet would not give me better safety, or am I wrong?
Hope this helps.
