dot vs. snell, great artical in the june Motorcyclist
they tested quite a few helmets and the results are eye opening. fiberglas shelled helmets vs. plastic, conventional thinking was the fiberglass was better at absorbing the measured forces transmitted to the head but in these tests the exact opposite was true. plastic shelled helmets actually performed better. the presumtion was that thepolycarbonate shells flex rather than crush and delaminate and this lets the shell absorb more energy rather than transmit it to your head. One paticular helmet the Z1R ZRP-1S which is under$100 did very well compared to all the helmets. the artical brought of interesting points of how the different test, Dot vs. snell, are not indicative of real world crashes. A good read
