Here's my experience with this. I shoot all three formats, frequently with
Tri-X. My experience is that there aren't dramatic differences in sharpness and
contrast between an 8x10 or 11x14 full frame enlargement made with top grade
Leica gear or a MF system. The real differences are in tonality, not grain. But,
there's one huge warning here. To get results this good from a 35mm you have to
keep in mind that you are working at the edge of the envelope, and you have
little if any room for error. MF is more forgiving because you aren't working at
the fringe of what it can do. These comments about quality don't hold true for
4x5. An 8x10 made from a 4x5 Tmax negative will give you a B&W print which looks
as if it was painted using mono-chromatic paint. Really beautiful.

I shoot T400CN or APX 100 for my 35mm stuff. I don't enlarge beyond 11x14
because I think that the image quality starts to fall apart at that point. I
don't use Tri-X for 35mm. I just can't take the grain. For 120 I shoot either
T400CN or Tri-X. For 4x5 I use Tri-X souped in Rodiol or D-76. I don't think
that 120 or 4x5 Tri-X is are the same emulsions as the 35mm variety. I just love
the results I get with larger format Tri-X.

I find for all these differences to become visible you need to get larger than
11x14 for 35mm, 16x20 for 120, and 20x24 for 4x5, or at lease you need to get to
this magnification level if you are doing smaller, cropped prints. Taste has a
lot to do with it, and your mileage will certainly vary. Some people are far
more into the technical aspects of image quality than others, and some kinds of
photography, such as landscape work, lend themselves to high image quality.
Others, like action photography, may not. Don't overlook the importance of
viewing distance, either.  Things look very different six feet from your nose
than they do at six inches from your nose.
