I avoid riding without one like the plague, one look at my burly old proteq bmx helmet will remind me with the quickness why I do, its covered, literally, in scrapes, gouges, etc. but still structurally sound enough to get the job done for bmx rides. for mtb or road rides I break out my equally old but luckily undamaged bell nemesis pro
definately a big YAY on the helmets!!!
besides I can't ride on base without one
