A lot depends on how much protection you want. Full face, 3/4 helmet, 1/2, skull cap are all options out there. A great deal depends too on if you run with a windshield or not as in, do you need a face shield? I have a variety of helmets and switch up depending on weather mostly. But I must say, I'm leaning towards my next helmet being a modular. Those seem to make a lot of sense to me.
