Interesting thread this as I've had similar thoughts. I've been using APH09 to process Delta 3200 and have been very happy with the texture, accutance and sharp grain. The combination of film and dev is very 1950s, just what I'm after and to me even nicer than Rodinal. I worked out a dev time and dilution that worked after a bit of testing. (1+25 17mins I think.) The bottle I've been using is now several months old and every month or so I've processed about 10 rolls of film. (The bottle never seems to go down-they should start making whisky!) I always put one roll through first, 'just to check' and certainley for the last two batches I have had to reduce the dilution and increase the time to get similar results. I've stopped using this bottle now as the negs are not as strong and have gone back to Rodinal. However, I've been trying out some Foma 400 recentley and the Adox 09 is fine giving very bold and contrasty negatives and I suspect if I put through some TriX or HP5 that would work too. Now I know Rodinal and it's ancestors have the repution for longevity so I'm wondering if the apparent oxidation and reduction in it's strength is only noticeable with a film like Delta 3200 which requires one hell of a lot more development than most emulsions. Anyone else tried this combination at all?
