Neal, I have just started testing with this paper developer myself. Also, using the 1+7 dil. with development times around 1 1/2 to 2 minutes at 70f. I really like the tones I'm getting with it so far, but have only used it on about 3 different negatives. It has all been with on Ilford MG IV RC and FB.
Some of the original prints of the same negs were done using Edwal Platinum II which I plan to use later on some Ilford WT FB (have already done some preliminary work on one negative).
