i went from a hybrid petzl back to a bd half dome recently .. the petzls foam cracked and it wasnt from a fall or rock
the BD does weight a bit more but it fits my head better ... i was considering a meteor ... but it simply did not fit my large noggin at all
IMO the hybrids are the way to go, both foam and a hardshell, for an all round helmet ... at the end of the day it needs to fit your head however, doesnt matter how light or cheap/expensive it is, or whether its foam/hardshell/hybrid ... if it doesnt fit properly
