Silver Rag may indeed have been updated. I was suppose to test some beta product a number of months ago, but because of my shoot schedule, wasn't available during the time period they needed. Not having seen a "new" box (I have a lot of "older" Silver Rag at the moment), I can't really comment. The sheet in between, though, is something they have used with the excellent Museo Portfolio Rag paper. It actually came in handy when I recently put together a folio of five images for a client. The "fly sheets" kept the prints from potentially scuffing each other. So the addition is a plus in my book. I believe they were testing a new coating that allowed for sharper ink dots and less paper curl. Crane actually still makes the actual paper, while the coating is made by the same original company (InteliCoat) which made it before, and took over the Museo name and product line.
Personally, I've tried almost all the "fibre glossy dried matte" papers out there, and still think Silver Rag is tops in the category.
