OK, I did it!
Tried some stand development with HP5+ and Ilfotec LC29 at 1:100 dilution.
Agitated for the first minute and then left it alone for one hour.
The negs came out somewhat flat and the scans (examples following) are quite grainy.
I never liked HP5+ anyways, that's why I used one of my last rolls to do this test. Now is it the film, the method (LC29 instead of Rodinal) or anything else? I don't know.
I have to say that I exposed the same roll at 400 ISO, with some pics at 1600 ISO. Nearly all came out OK. Now is it the latitude of the film or the stand development that did some small miracle? I don't know.
Tell me what you think of the results please!!!!
Here are some of the results - just some random snaps and some tweaking in Aperture:
