Stone, if I gave you the impression they'd be B&W, I'm sorry. If it was me, I likely said mine would end up as B&W because that's all I can print in my darkroom.
I haven't gotten streaks across mine like that one Jonathan, but I've done some that had been sitting for a few weeks at least. I have a couple sitting here that have been sitting for maybe a month or two that I haven't done, yet. I think the age at processing might be a part of it as well as time between initial processing and recovery. I've mostly used non-expired stuff for these.
