Photographers' Formulary has an improved version of FX-2 (I believe they call it SFX-2) which works well for compression development. They market it as a high acutance developer, but dilluted 50ml per litre it is also compensating. Because it contains glycin (which resists streaking) you can also back way off on agitation for additional compensation--they recommend 10 inversions for 20 seconds every three minutes. I've had good luck and extremely high sharpness with it.(posted 9014 days ago)
