Ilford Perceptol alias Kodak Microdol-X is not too bad in terms of acutance, and it becomes pretty good at 1+3. But with most films you lose some speed. And of course it is not as comfortable to use as Rodinal and does not last for centuries.
That's just it though. I want the best of both worlds... extremely high acutance and fine grain. By far, I care most about acutance and would never give that up for fine grain. I'll just shoot the biggest film I can carry the equipment for.

If there is a very high actance developer (at least as good as Rodinal) but with finer grain then I would certainly give it a try.
