Response to Ilford DD-X vs Ilfosol S

Based on my experience with Microphen (which is allegedly a powder form of DD-X) and Xtol (very similar to Ilfosol-S) you won't see a difference between the developers with slow film. I normally develop TMX in Xtol diluted 1+2. I tested TMX in Microphen to see if I would get a speed increase as I do with TMY (~2/3 stop). I got no discernable speed increase with TMX in Microphen and no difference in grain (very slight increase of grain with TMY vs Xtol in Microphen). In fact I got the same development time for TMX in Xtol or Microphen, both diluted 1+2 (11 min, 75F). I've considered dropping Xtol and sticking with Microphen. I haven't worked out the costs since it's such a small factor to me.
