If you just want to dissolve a small quantity of phenidone quickly, dissolve it in a few ml of isopropyl alcohol (70% from the pharmacy will do) and add that IPA solution before making up to the final volume.
POTA is sure a pita.
My backordered Phenidone arrived this weekend so I mixed up a small batch of POTA and souped my Adox CMS II in it. It worked and I have negatives to print but mixing the phenidone into solution was a major pain in the neck. It certainly does not like to dissolve into solution. I must be doing something wrong because even after 15 minutes of constant stirring I still had undissolved solids from the Phenidone.
I developed at 77F for 11m agitating for the first 45 seconds and then three times per minute following that. From the looks of the negatives I have plenty of contrast so I may end up having to tone down the number of agitations and/or the solution temperature.
To easily dissolve phenidone, add to it a few ml's of isopropyl alcohol. Stir it up in a separate container. This is how I've always mixed phenidone when making pyrocat-hd.
Thanks Andrew. I decided to use some propylene glycol this time around and it seems to be working out well. Haven't had much chance to shoot CMS ii in 35mm lately since my 8x10 has been consuming most of my time but I will get back to this soon.
I should pick up a box and give it a try in 4x5. Caffenol is an option I haven't really given any thought but it might be interesting to try. You should post a scan of one of your prints if you get the opportunity.I developed a 4x5 sheet of CMS 20 II yesterday in Caffenol LC. Semi-stand. It came out quite nice. Today I'm going to give POTA a shot.

Of course if I shoot some CMS 20 ii in 4x5 I may actually have to scrounge about and find my one good lens in order to do it justice.
Hmm...more ideas than time.

I do use Adotech and so far I prefer the results when using that developer, .
Yes. I have read his recommendation and he is right on the money.Henning Serger certainly seems to rate the Adotech developer above others. While he rates most Adox stuff highly there may be something in his high rating
With CMS II and 4x5 sheets, I imagine the limit of enlargement for a decent print doesn't exceed 8x10 but I don't know if this is feet or yards?

POTA. 4x5 CMS 20 II. EI 10. Reciprocity correction added. Total exposure time 80 sec at f/22. Agitation 5 sec every minute. Tray. 24C. I've ordered a couple of bottles of Adotech IV to compare.

I play around with other developing alternatives from time to time because I enjoy doing it. But when push comes to shove and I absolutely need the pictures I use Adotech. Especially if I need to do any serious enlargements. Of course my enlarger has been out of service for over a year now so most of what I have been doing is play.
IMHO Adox has certainly done a great job with this film/developer combo. I am trying to get a little cash together as we speak so I can give the 4x5 a try. Of course if it works out as well as I think then I will have to get my enlarger set up again.
I am finding this developer very curious and interesting for Adox CMS 20ii. I was planning on trying out the combo myself. Thank you all for testing this so far. I will do my own tests and if that's alright, post them here?
Mixing up some POTA today to develop a couple sheets of CMS 20 II.
Do you pre-flash CMS 20ii?
There are several interesting alternatives to POTA in the Film Developing Cookbook.
There was also a thread here with the title "A very low contrast, low pH, full speed POTA variant", but it seems to have dropped of the face of the internet. The developers tested in this thread were all (if my memory serves me right) 2 g Dimezone-S, 20 g Sodium Sulfite, and 1g of some secondary developer like Ascorbic Acid, Pyrogallol and Hydroquinone. They all produced beautiful straight flat characteristic curves.
