I like to shoot Pan F+ at EI 64 and develop in Diafine. This also tames the contrast nicely. I don't know how it would compare to 32-40 in D23 1+1, not having tried that. It's a great combo IMHO but it's not Pan-X.

For Christmas I gave my wife's parents a mounted and framed print 15" square from a 6x6 negative on Pan F+ in Diafine. Even up close it appears grainless.
