I have some experience with Emofin, did not use it on Tri-X. I use it as a speed increasing fine grain developer on HP5 and TMY, both exposed at 1600. The developing agents in Emofin are rather fine grain, low acutance. Using Emofin on a film at ISO rating with regular times gave pretty low contrast, which is no good for soft enlarger, but Push 2 gives good contrast.
Have you considered Diafine for TX? It is supposed to give a speed around 1250.
These both two bath developers are only useful in my point of view if you are looking for a speed increase. If you are just looking for plain old 200-400 ASA there plenty of other options.
