Which helmet do you use?

I think if you get a helmet from one of the major makers, and/or you're sure that is has passed all the noggin protection tests, you'll be fine.

I still have the box from my dearly departed Bell Furio and the price tag on it shows $55, altho REI has it for $64.

$50-ish is probably a good lower price point for a well-made helmet. Not sure what you get with the pricier brands, but I'll be checking them out as well, in case I'm missing out on something.
