I used FX-39 II with Fomapan 100, Fomapan 200, Kentmere 100 and Adox CHS-100 II. Good sharpness and contrast. The contrast can be reduced by using the high dilution 1+19. This is especially useful for Fomapan 100.
About FX-39 II, I disliked the grain. Both Fomapan 200 and CHS-100 II came out with grain I did not like. For high ISO films it may be even worse.
I switched to Adox XT-3. Overall very good results with all films I used. I am very much satisfied with it. Even Adox HR-50 can be developed in XT-3 (1+3, 16 Min.)
