I too just received a 9900 and have tried several media with mixed results. This thread was very helpful in explaining why. The Epson Ultra Smooth was great as was the Exhibition Fiber after someone sent me a profile. I have had great success with Ilford Gallerie Gold Fiber Silk on my 4800 but not so good on the 9900. If someone has built a profile for this combination it would be most appreciated since I don't have a spectrophotometer.
Thanks
