I'm going to derail this a bit.

Some friends of mine are in an MTB group and one of their rules is nobody with a kickstand is allowed to be a member. I'm friends with a couple of guys who wanted to join but were turned down for this very reason. I'm buds with all of them and after I designed a logo for the group, I was invited to join. I told them I put kickstands on all of my bikes, but thanks for offering. After some good-natured ribbing, I sent them a second logo. I've attached both.

Back to your regularly scheduled helmet debate.
