I know this thread is old now but... I received a sample pack from print carrier not so long ago. I was interested to see what their opaque and tear resistant stock was like and to be honest the whole pack was mediocre to say the least. The 'special' papers such as the tear resistant were really poor quality (ie; warped & curled, not cut straight).
Oh and does Boss have no control over which companies appear in the adspace on the forum pages?
