Unfortunately, the only options in this case are to have a lab print my work, which is too much of a drain on time and money compared to my own darkroom, or to print via inkjet, which is too much of a drain on time and money compared to my darkroom.
I can work around this VC paper's attributes. I'm not married to the current Supra so much that I can't print anything else. The lack of sheet sizes, however, is a serious problem. And not just for me.
