A helmet is something that you hope you never need, but in the event that you do you always wish you had a better one. It's a trade off between comfort and protection. If your a firearm guy you could compare it to carrying a gun. It's easy to carry a little pocket pistol but if you get into a firefight the more gun you have the better. Same thing with helmets. For me personally I switch between the half and a full face modular. I will never ride without at least the half helmet even if I'm in a state that doesn't require it.
