Well I finally decided on a Louis Garneau Exo-Nerv for a couple reasons:

1. most important, I can get my hair through the back

2. it's very comfortable, with no identifiable pressure points, yet

3. the straps are really soft - that's a bonus

4. it looks pretty good on my head.

5. and the price point was within my budget.

The Giro Atmos was also a nice helmet, but it was a little too expensive for me and it a little like a mushroom resting on my head.

I liked the Lazer as well, but I could only find the O2 line which was a one size fits all, and really looked too big as well.
