The Weight of the paper is 300 gsm.

Yes - Markus came by and I showed him some samples of the silver rag paper comparing them with luster and smooth pearl and we both agreed this stuff has a better "feel" to it and is damned close to a fiber print. I framed a small version of Night Storm on the Silver Rag so it would be under glass, and I know this print very well - and you would need to know what to look for in order to distinguish it from an Ilford Gallerie Fiber print. The paper is 100% cotton, has a heavy enough feel so that you aren't going to run into rippling or other effects due to humidity or lack thereof - and it has a presence which the plasticky RC type papers don't have. As I said to Markus - it makes me want to get closer and really look at the print closely.
So let's hope it hits the stores soon - and let's see what it costs. I hope to do some testing with the roll version I got yesterday to see how it goes through the printer and what the curl is like.
