I just had someone else write me today about mottle/surface issues with the current Oriental paper, so there must be something going on. I'l see if I can find out anything.
In the meantime, I have been using nothing but the Ilford MGFB for printing the Ansel Adams Special Edition prints for nearly thirty years and have always found it up to the task. I experiment with other papers for my own work from time to time, and the last time I used Oriental (a couple of years ago) it was very good.
I have found the Ilford to be the most consistent paper I have used over the years. You can experiment with some different developers to see if you find any color shifts. You certainly can't go wrong with Dektol as far as image quality.
Good luck!
