Well, after looking, and trying on lots of helmets, I have finally found one that fits my oval head. Arai Profile
http://www.araiamericas.com/helmet_details.asp?model=PROFILEIt's not a flip-up, but I just couldn't find a flip up that fit me. I did find the Nolan X1002 and thought I was headed in that direction until reading a review on the site below that stated that it was one of the noisiest helmets they tested.
In my research, I came across a great site, with a TON of good helmet info. They have a lot of reviews, fitting instructions etc. This is where I learned that for someone with an oval, instead of earth shaped head, the Arai Profile would be the best fit. I tried one on yesterday, and it truly fits wonderfully. I've never put on a helmet that was contoured so perfectly.
The web site is Web Bike World. Here's a link:
