Speed difference between Acros II, TMX, and Delta 100 at same CI?

Pan F is the one with the worst latent image characteristics that I'm aware of. No need to panic, but I certainly wouldn't leave it laying around for six months before processing. Been there, done that, and regret it. One or two months shouldn't cause worry.

On the other hand, I've stumbled onto forgotten exposed sheets of TMax, Acros, and FP4 several years old, and have successfully developed them without fog or other complications.

I once considered replacing Panatomic-X with Pan F but heard so much about Pan F latent image loss that it scared me away.

Now I can see latent image loss over time, and I can adjust processing (give more time for older images) to reduce its impact.

I suppose I could test some Pan F. I still have a sealed bulk roll.

Well, wait too long after exposure with Pan F, and extra development won't do you a bit of good. It seems to store decently prior to development; but there's this newfangled worry thing about 120 liner paper itself causing issues if left around too long.
