Well at EI25 any film is likely to be more problematic with strong dillutions of developer. For example they don't even list times for Adox/Efke 50 with Tmax 1:4 because the window is so narrow under 5 minutes I think.

If I go with Rodinal at 1:50 or 1:100 my area of 5.5-6.5 to play in becomes several minutes wide.
