As much as I will always vastly prefer a folded copy over a linenbacked one, I can see the benefit of using linen for large paper (such as 3-sheets and 6-sheets, as well as Italian 4F), since the added support makes handling and framing easier. However, I really don't understand the need to put one-sheets on linen, unless it's in such a poor condition that there is no other alternative to preserve it. Most of the linenbacked one-sheets I see on the market certainly do not warrant such a treatment, at least in my eyes. To this day, even though I have relented on my anti-linen stance when it comes to large paper for certain titles that are impossible to find otherwise, I have not acquired a single linenbacked one-sheet (even though it's getting increasingly difficult to find folded copies for certain titles that I'm looking for).
