It's grainy for its speed, no matter what you do with it (well, I guess if you put it in the fixer first you won't get much grain, but short of that... :-) I usually shoot it at 50 and develop for 8:30 in PC-TEA, which usually has the same dev times as Xtol 1+2.

For larger formats it looks really nice in Caffenol developers, but in 35mm I expect the grain would be intolerable. You could always try a super-fine-grain developer like Perceptol and see how you like the results, of course.
