I've tested T-max (and Delta) and I didn't liked its structure in mid range grew, so finally it was sorted and I was hooked to Tmax 3200 at 1600. But that could be easily done even better with Tri-X, so Tmax was sorted, too.
Ilford's Pan F+ is very good, I like it very much in bright sun, but with Perceptol it is fixed to 25 ASA which is a bit too limited, but a very good option! So I have to try the filter thing with the Rollei RPX which sounds, after the basics I've first to do with Rodinal, very good.
