Use a 25A filter

I'd suggest you also try Agfa's APX-100, and since you're using a
tripod, also Efke KB-25.

T-Max developer does not produce much acutance effect. For
that you want a Metol developer without hydroquinone in it.
You will get more grain but T-Max and Delta films are fine
grain enough to tolerate something less than the finest
grain development. Developers like Microdol-X at 1:3 or D-23
at 1:3 (have to mix that yourself) will produce lots of
acutance. Acutance is an optical illusion. The eye perceives
edge contrast as sharpness. Even when the _resolution_ of a
film is high it may not look sharp because the edge contrast
is low. The chemical effects which tend toward fine grain
also tend to prevent the effects which lead to acutance, so
some compromise must be made between fine grain and
acutance. This is not generally a problem with formats
larger than 35mm but certainly is for that format.
Conventional films, like FP-4 or Plus-X have thicker
emulsions than tabular grain films like T-Max and Delta so
are more likely to have acutance effects, again at the price
of more grain.
 The reason for staying away from Hydroquinone containing
developers is that Hydroquinone tends to reverse the
chemical effects which lead to acutance, especially in
developers where it is active, such as DK-50 or T-Max.
Hydroquinone developers, where the Hydroquinone is inactive,
due to low pH, such as D-76 and ID-11, will produce acutance
effects when diluted to 1:3. However, I find these effect
unpleasant. D-23 is IMHO a better choice. There are other
developers especially formulated to exagerate acutance, but
they work best on old style thick emulsion films.
 You will have to experiment to find which combination is
pleasing to you. Nothing is going to give you the detailed
look of L-F on 35mm film. Any negative larger than 35mm will
give you a noticable improvement in sharpness, fine grain,
and especially smoothness of tonal rendition. 35mm works
well for note taking but something else will work better for
a back-up.

I would use XTOL 1:2 dilution. This gives excellent film speed so you may
need adjust accordingly. Kodak no longer publishes times for 1:2 dilution,
but you can find times elsewhere or do your own testing (which you should do
anyway).

I tried D100 and Apx-100 in FX-39 ( 1+9 ) developer and was quite pleased, as a
matter of fact I liked both of these films in FX-39 better than X-tol. Of the
two films I must say that I liked the D100 best.

I'm sure that you've gotten an answer by now but you may want to think about
using 35mm Tmax with the Tmax developer. I've found that the only thing that
Tmax and Tmax-rs have in common is the name. I also think that Tmax is a better
developer.
