I think that you should offer better quality 11"x17" paper and not restrict your customer to one brand of paper (yours). Your brand lacks a lot. I would have purchased Hammermill Color Copy paper in the tabloid size if you stocked it. Forcing people to use poor-quality paper will just force your customers to find the quality they seek elsewhere.
We use this paper to print variety of personal documents. The black and white and some color printing appears to be reasonably good. We mostly print on one side.
