Okay, I'll start with a confession: I'm lazy.
I did do my own tests with the new Tri-X emulsion in 4x5 with Rodinal 1+50 using intermittant agitation (for compensating effect and acutance). I got some delightful results - if a little grainy (even in an 8x10 enlargement). The lazy bit is that I also processed some duplicate negs of Rodinal-processed shots in Jobo Expert drums using DDX diluted 1+8 and following Phil's Data. The density range in the negs was identical and each neg printed exactly for the same time on the same grade filter to yield seemingly identical prints with the small exception that the Rodinal had better separation in the low values and a little more lift in the mid-tones. Otherwise the end points matched extremely well to the eye.
So I have these questions since I wish to pursue the DDX approach because the grain is far finer and less obtrusive and there are few other developers but DDX & Rodinal that give a range of workable times with Tri-X:
Does anybody know the approximate composition of Ilfotech DDX?
Is there a way that I could modify working with DDX and constant agitation to increase low value separation and lift mid tone contrast?
Do others find other workable combinations for working with Tri-X in the low-volumes of chemistry of tube processing systems?
