Like i said in the other thread, quality of paper makes a huge diff. I've bought the cheap shit before, and there is a reason I don't anymore.... it just doesn't work as well. Some times the laser burns a hole in it rather than igniting it, it burns really slow and does leave ash, it clogs up my DIY flash cannon.. not worth it IMHO. I have some stock of Black Magic coming in hopefully today or tomorrow, see my for sale thread in the B/S/T section if you're interested.
