Full or Open Face Helmet?

[Zoodles95_imp]

I ride a vintage 1981 CB 750 Custom and I wear a full face helmet. I think this image kind of sums up my thinking:

I did long haul trucking for awhile and would come south to deliver goods from Canada to the U.S. It always amazed me how many motorcyclists I saw sans helmets.

This is a dangerous hobby/sport/lifestyle/obsession etc so I try to mitigate the risks where I can. Using a full face helmet is a no brainer for me. However, I respect other's choices.

And that 19.4% is just the right side of your chin. Don't forget to add the 15.2% for the left side of the chin.
