Thanks very much for the feedback. I will return the S3.

I will move on to Bell -- I can order the Volt from my LBS or REI, and can easily return it to the store if it doesn't fit right. Plus both have loyalty programs so I'll earn a future discount with the purchase. In fact I might be due for 10% off a purchase at the LBS, I'll have to check.

I remember Muirenn mentioning some Rudy Project helmets in my other recent helmet thread, but there are no stores around here that carry them so a return would be more expensive if it doesn't fit. So I'll try Bell first.

This is harder than it should be...

BTW I checked my old Pneumo, and there is a one-finger space between my eyebrow and the helmet. I will use that test with any other helmets I try.
