I'm really perplexed by the reports of bad graininess with HC-110/Ilfotec HC. I have never had a problem with it being grainy. I don't know how many times I have heard someone say of HC-110 something like, "That stuff is horrible crap. I use a real good developer like D-76 instead." Aside from the working EIs being a third off from each other in my tests (ID-11 1:1 made for the higher EI than Ilfotec HC 1:31), I can't tell the difference between them. I use HC instead simply because of the convenience and longevity. Kodak has a chart that compares their developers, and if my memory serves me correctly, the chart sez that D-76 caused higher levels of grain than HC-110 in their tests. (I do not remember the dilutions, however.) Also, I have never found HP5 to be particularly grainy either. HP5/HC is my most often used combo in all formats, and the grain has never bothered me even when pushed. I guess it really depends on the individual's methods and grading criteria. You can squeeze some nasty grain out of HP5 if you grossly overexpose it. This is what I do when I want gnarly grain, and I shoot Delta 3200 when I want a more neat grain pattern.
