OK Jon, I read your answer on BC. But when I go to the poc site both the snow and bike Cortex DH look the same. Is the difference just a mater of what year it was made or does poc have a dedicated DH for snow and a dedicated DH for wheels? If it is just a matter of changes made from year to year, is there a good reason I should not get the DH from Huckn Roll instead of BC? Thanks for taking the time to answer.
