hmmm well I guess I'd have to say I've been riding with a 1/2 helmet and a full face lid, I like my full face when the weather turns crappy , but in the heat of summer the half helmet is my friend, but I wear armored jackets all the time with heavy jeans and boots, sometimes chaps... I don't worry about catching rocks and such because of my windshield, but I do suppose I take a risk in a crash not wearing the full facer... it's a matter of personal preference really... do research find what works best for your situation, and don't be afraid to have more then one helmet.... I've got 4...
