Thanks leix45 for your comments and question.
As for my choice B/W films: for 400 Iso film today I only use TMY-2 (latest T-Max 400) 135, 120 and 4x5" I think it's a great film, not just the emulsion, but also the very base is nice to work with (if all b/w film were to disappear from the market, but one left, I think I would vote for keeping this very film! On the othe hand it was a long time ago since I used the Ilford films, which probably are quite as good to work with). Today TMY-2 is the only film I use as 135 film.
When Fuji's Acros 100 appeard on the market I tried it on 120 with Rodinal and liked it very much, still my standard 100 ISO 120-film. It has a thinner base, not as nice to work with as TMAX films, but I think, in relation to T-Max 100, it's sharper and almost without grain, evan with Rodinal, which is a developer I like to use (together with old D-76 and D-23, have stopped experimenting with other developers! Pyro developer seems to be little hard to get in Sweden, so I haven't tried them, also not sure how the work with mulitgrade paper which I prefer to use).
I also do some LF in b/w and, save 4x5" TMY-2 , my standard film is Fomapan 100 (4x5", 5x7" and 8x10", half the price of Kodak/Ilford films and sheet film is expensive enough) normally developed in Rodinal (but also D-76 and D-23).
Back in time I have tried most (normal) films on the market, liked AGFA 400 very (with Microdol-X), much but also ORWO 100 (with Rodinal)!
Best wishes
