Here is the way I do it:

Kodak Technical Pan Rodinal
I was given three rolls of 35mm Kodak Technical Pan (expired 2002). I hunted around for a development scheme and finally settled on this. Mostly because I had Rodinal. I'm only posting in case some of you still have some in the fridge.
16 EI
Rodinal 1+150 for thirteen minutes
Agitate with 30 seconds initial inversions, then 3 inversions at 10 minutes,7 minutes,4 minutes, and 1minute counting down. (every 3 minutes)
Regular stop, fix and hypo.
I used 5ml of Rodinal in 750ml of H2O. That gives less than the recommended 10ml of Rodinal but the negatives really look great (full tone scale).
I had to figure out a curve profile as I felt (and still do) that the midtones were not right. Technical Pan is also a dust magnet; lots of healing tool. Even with Rodinal there is virtually no grain.
EDIT:
With this last roll I used a Yellow filter which made life easy to post process.
