I have done option A to fiber prints many times. Not the best thing of course, but better than option B in my opinion. I feel that drying the print with residual fixer could create a wash out problem. Also, option A is not for RC paper at all. Someone came into the lab where i worked once, with about 50 RC 5 x 7 prints that had frilled on the edges. At first I was at a loss to explain it, and then I asked her, had they been in the water long? She said over night. I said BINGO.
