....not necessarily bad - a rigid shell will transmit more energy into the helmet liner (and thence into your head) whereas one with a degree of "give" will absorb the energy as it deforms and degrades...if ya really wanna get paranoid, check these out... helmet study 1 and especially helmet study 2 - the Cooter study reckons you're more likely to die from wearing a full face helmet...anyway, mate, you decide!
Never whistle while you're ******....!
