I believe that Microdol-X is a grain swelling developer, as opposed  
to a grain etching developer. That means that there will be an  
appreciable resolution loss with any film developed with it. Once  
upon a time we used to call the developer Mush-X.
Also, film which is to be developed in Microdol-X has to be over- 
exposed by a slight factor in order to account for what is termed as  
emulsion speed loss. That means one has to know before hand if  
Microdol-X is to be used.
Tri-X, an emulsion that already has its own issues with resolution,  
won't be well served with Microdol-X.
