Simon thanks for this reply and I look forward to hearing about the tech dept's findings. Allegedly was a tongue in cheek use of the word but my sentiments would have been better expressed if I had said that I was attempting to take an impartial position and "sit on the fence" until the evidence was much clearer.
For others interested in this matter, I have just done a quick search of APUG on the subject and roughly for every person claiming that there is an issue with PanF+ compared to other Ilford films there is one who has had no such issue. The numbers involved was small on both sides
You learn a lot in a search, including now a healthy doubt on my part, based on your response, about those saying things such as "from Ilford sources" in this context.
I stand corrected. Trusting to memory is rarely a good approach, certainly not in my case. I look forward to hearing the official word.
