I don't think the little extra comfort should make you choose not to wear a helment. I thought about this a while ago and it is so stupid not to wear one, you could have some sort of freak accident and die. And then that's it, it's all over. What happens then? Well to you... no one knows, an afterlife maybe, nothing, heaven/hell? And what happens to those close to you? They mourn for you, they loose you and are hurt, and they will never ever have you back. Only memories of you will be around.
So don't be stupid, protect your head and wear a helment.
Cheers,
