Full face, there are some big bugs and lots of debris in the road. Also, get your head measurement. Many wear larger than they should be, I was one of those. It's not enough to put on the helmet and try to shake it left and right! It should be a struggle and then it pops on. Shove the front towards your face. If it makes any contact, it's very likely to punch you in the mouth or shove your nose into your face and crack an eye socket. I had blood out the nose and ears and a shattered eye socket, along with a subdural hematoma, contusion, amnesia and spending about 1 1/2 weeks as a live action coma. 40 mph or less.
