Henning,

This is news to me. But I think similar treatment is the key phrase, here. 
TMX is a unique film. IMHO, properly exposed TMX negs look thinner than 
other negs (which is difficult to get used to). TMX seems to like contast 
agitation, ie rotary processing. It's very responsive to changes in 
developers, as well as  development times. It may not like some developers, 
I don't know. I've only used it with Rodinal, TMAX, D-76 and XTOL. A 
difficult film to master, perhaps. But capable of very high acutance.

Delta always has had a reputation for high acutance, due, from what I 
understand, to it's thinner emulsion. But I've never seen it to result 
in  sharper looking prints than TMX. At least not using any of my workflows.
