I'll always support people's rights to choose what kind of protection they want to wear, however after my spill, I'll always wear a full face helmet... Wrecked a sports bike doing about 50 on a mountain highway, spill ripped through my armored glove and broke two fingers, one of which required pins and several months of PT. Helmet saved my life though. Rolled off the bike and slapped the back of my head on the asphalt, without the helmet I would be dead for sure.
Like I said, I'll always support individual rights to wear/not wear gear, but I always advocate for Full gear on every ride.
