If I want a fine grain result, I use a fine grain fillm.
As I said earlier in this thread, I shoot TMax 100 and Acros on a tripod and develop in Pyrocat-MC.
If I'm shooting my Mamiya 7 II hand held, I shoot Kodak TMY 400 or Fuji Neopan 400 and develop it in Pyrocat-MC. The acutance is high, the tonality is great and the grain is not super fine, but is acceptable to me.
Crawley's FX-2 works well with Efke 25 (but then, so does Pyrocat-MC and Pyrocat -HD).
