I discovered the existence of this article: http://connection.ebscohost.com/c/articles/78093864/ilfords-mg-art-300-traditional-printing-paper
but can't seem to access it. The beginning of the abstract states: "The article presents the author's experience in making 8x10 contact prints with the use of the newly introduced Ilford Multigrade (MG) Art 300 fiber based paper"
I'd assume that because there is a whole article on it the experience was positive or at least not wholly negative but that's not a lot to go on.
