I'm not sure if I would shoot Pan F as a sheet film, I've been more than happy with 5x4 Delta 100, and amazed at HP5 in Pyrocat HD, which I've been using for hand held LF work for around 19 years.
A lot depends on how large you print, here in the UK few photographers print larger than 16"x12" or 20"x16". In the past I printed much larger for work,
In the US some photographers are making very large prints, Clyde Butcher is printing up to 52"x76", so shooting Pan F would make sense, especially if it was added to the annual ULF run.
I have a few 120 rolls of Pan F and plan to start shooting it in my 6x17 camera, So will be interested in the resulting print quality, particularly now I have a Centre ND filter for the 75mm Super Angulon lens.
My favourite Ultra Fine Grain film was Agfa AP25/APX25, I used it in a 6x9 roll film back with my Wista 45DX. I also use EKE PL25 in 5x4 & 10x8, it's actually a 50 ISO film in daylight, 25 is the Tungsten light ISO. So I'm not adverse to UFG slow films, where I can use a tripod.
So perhaps I would try a box of 5x4 Pan F as I've almost finished my 5x4 PL25m 2 boxes of 10x8 left
Let's see.
