Giro Nine. It fits. That's what makes it good. The removable vents make it better.

Funny, I've found the Boeri to fit my long, narrow head perfectly while the Giro's are too round. Stick out on either side. Goes to show you need to try 'em on.
About the construction concern: Some threads from Trekchick this summer have great links to sites that discuss design/materials/medical issues. Worth searching out. My sense is that it's less about the outer shell per se and more about how the head moves around inside upon impact.
