i think o6 got a bad rap too... the majority of o6's i have felt are nicer than the o8's i have felt. it's all a personal opinion though. the o6's i have seen are thinner, more marbled but very soft... whereas the o8's i've seen are thicker and stiffer (not as soft). but i am sure it all varies, it could be that the NM's i went to got a bad batch of o8's
