A lot of mixing of oranges and apples here. Pan F is a very slow film (typically ASA25) with a long toe, early shoulder, and short straight line, so needs very careful exposure and development, and is
probably not the best choice for high contrast scenes. FP4 and ACROS are long-scale medium-toe
films which I personally rate at 50 for pyro, but differ in spectral sensitivity - ACROS will deliver slightly finer grain, but both films are lovely. TMX100 is a fairly high contrast short-toe film which should NOT be overexposed or it can shoulder off, but will deliver excellent shadow gradation. TMY400 is distinctly grainier, but for its speed very fine, and an excellent all-purpose film if you like a
relatively long straight line rather than a more gradual toe. I've used all these fims in everything from
35mm to 8X10, with the exception of Pan F of course, which is only avail up to 120 size. Each has
its own personality, though I'd call all these films excellent in overall quality.
I agree, it's a reasonable fix, I may even have to try it some.

Actually this (the short roll approach) makes zero sense to me, but the reason was clear on 10 seconds of thought. I agree that it makes sense for you. The difference is in our reasons for wanting the shorter rolls.

There's often months delay between my shooting and getting to process the film (stored refrigerated in the interim and I try to get to Pan F+ and Delta 3200 sooner but even they can be weeks.) If I just wanted to process the shots now I'd cheerfully do what you do and never even have mentioned it here.
Rather, my reason, especially with slower films like we're talking about here, is almost always because I want to load a different film in the camera. I have three 35mm bodies I regularly use but still often don't have an empty one or one with the film I want to use when I next shoot. I do mid roll changes sometimes, just rewind the film but leave the leader out and write a note on the leader about the next frame number, then when I reload click off, with the lens cap on, all the already shot frames plus, typically, one more to be sure. If you are consistent in how you load the camera this works, and probably wastes less film than loading shorter rolls, but I still find it rather annoying.
Actually what you propose, while it will work fine with factory loads, is risky with bulk loaded film anyway, at least if you use a daylight loader in daylight. The reason is that the tail of the film, not just the leader, will be fogged and if you pull out part of a roll in the dark and re-trim a new leader it will be almost impossible to tell exactly where the unfogged loaded film ends and the fogged tail begins. I suppose with practice this could become pretty apparent but without practice at this you'd risk making exposures on the fogged film tail.
I have done exactly what you say with factory loads, though.
Thank you, that is very good advice! That makes sense too.

Sometimes I want slow emulsions, other times fast emulsions, sometimes I want to push, and sometimes I want color. It depends mostly on what the lighting demands. I'm usually not so particular with 35mm and I can compromise, but only to an extent. Your advice is very good and I think that I should take advantage of mid-roll changes.
I've used Pan F+ for years in 120. I live in LA so we have plenty of sun for me to rate it at 25 and still get shutter speeds of 125 and higher. Yes, it does take some time to get used to, but once you do, it's a great film. I use Rodinal 1+100 for 18 minutes with regular agitation. I've also kept exposed rolls of Pan F+ in my freezer for over a year and they came out fine when developed.
