I was an advocate of FG-7 for a long while too (until I couldn't get it in Hawaii for hazmat issues -- JUST LIKE RODINAL!!!). There's also a variant for tabular-grain films, it was a longtime favorite with Delta (my standard kits in the early 90's: rodinal/tg-7/hc-d)
Well, ya know, good old D-23 has so much sulfite in it that it smooths and reduces the grain quite well. It is one of the simplest formulas around.
I'm with you on this. D-23 - with optional borax afterbath - is has the simplest of all formulas (opposite of Rodinal), gives very low acutance (unlike Rodinal), smooth "mushy" grain (unlike Rodinal) and is very, very cheap (unlike Rodinal). If used with the borax afterbath it lasts just about forever (as working solution, unlike Rodinal)...
Although I'm doing everything in either Rodinal or Pyrocat-HD these days, another possibility for the characteristics you're looking for is undiluted Perceptol. It was my old favorite for these sorts of things before I discovered Pyrocat-HD.
Microdol-X is still available and it is probably the closest thing you'll get to an opposite of Rodinal. I don't like it much either since I don't have any real use for it. XTOL or D-76 fit the bill perfectly for me.
