Which modern Rodinal clone?

[ChrisPlatt]

There are several claimed Rodinal clones available from various manufacturers. Freestyle lists nearly a half-dozen. I am confused.

Which one(s) are most like the old Agfa-Gevaert formula I used, particularly in regard to the shelf-life of the undiluted concentrate?

Short reviews and recommendations appreciated.

TIA,
Chris

I don't know if it is like the original, but I have had good luck with R09 One Shot. Good shelf life undiluted.

Same with me - bought a R09 in 2009 and used it for a few years before switching to HC-110. Last July i used that 2009 bottle and it was fine.

I could certainly be wrong about this, and would love to be corrected by an authoritative source if so, but aren't they all pretty much identical, yielding identical results?

This one is the same formula AGFA was selling before they closed their doors.

I have also used the Adox APH-09 formula, which is claimed to be the pre-WWII formula of AGFA Rodinal. I got identical results from both.

I was always under the impression that they were identical?

I use Foma R09 purely because it's readily available locally.
