The great thing about scanning versus classic printing is that we don't 'need'
accutance anymore: do the sharpening in the (highly controllable) computer
rather than the (relatively uncontrolable) developer bath.... But sharpening
effects are little compensation for unsharp lenses, csi magic notwithstanding!

If you want the finest grain use a combination of any
of the 100 speed tabular grain films like 100T-Max or
Delta-100 with Perceptol or Microdol-X full strength. The
combination will give you nearly as fine grain as the late,
lamented, Technical Pan but with about four times the speed
(EI-50) and much easier to control contrast. The combination
will begin to give the kind of smoothness of tone rendition
for 35mm that one gets from larger negatives. However, there
is little or no acutance effect so you need good lenses for
sharp images.
As far as I can find out the formulation for Perceptol
is identical to Microdol-X. I can't be sure because there
are often ingredients that do not have to be shown on the
MSDS. However, both rely on sodium chloride (yup, table
salt) as the fine grain agent. When diluted 1:3 either
becomes an acutance developer yielding a considerable
sharpness booste and full film speed but does not have the
extra-fine-grain property it does when used full strength.
