Oh, I miss it so BAD... :-(
Besides the extreme resolving power and lack of grain, I also liked the TP
because of the extended red sensitivity -- a must for astro pics. Now I'm
trying Rollei SuperPan 200, which is much faster, has _some_ grain but a
similar response. Time will tell.
However, if I want to use TP with a "normal" contrast, the only way I know
is to develop it in Technidol, which if discontinued probaby would last much
less than the film. B&W film can last quite a long time -- I'm using (for
quick tests etc) a roll of Adox KB21 (now Efke 100) expired in 1986...

Yes, instead of the usual 100ft = 20 rolls because of the thinner Estar-AH
base allows that 50% extra per roll -- you could make 50 exp. rolls or so!

Seems
difficult. And, as stated in a previous post, I would like some "real
world" conditions.

Even in paper developer... but always with a high, harsh contrast.

Seems a sensible option. Anyone here has experience with Ektar 100?

Oh, Kodachrome... years ago I had a roll of PKR64 returned... I don't think
I could develop it any more :-(

Well, although my most used film is Tri-X @ 1600, I _sometimes_ go much
slower, like Delta 100 or Pan F. These were some of the considered
options in this thread.
