Generally speaking, the lower the film speed (the sensitivity of the film
to
light expressed as "ISO"), the finer the film's grain. Check with the
manufacturer to determine the finest grain, usually expressed as line
pairs.
I have never used a film in the manner you are exploring, so I can't give
exact answers; I can only answer in terms of 'pictorial' use of film.
