P.O.T.A.
The system keeps auto-changing the letters to lower case, not sure why, so I added periods, but it's spelled without the periods.

After much experimentation this is the best I have found

I've used TD-3. I was very happy with the results.
I still have Technidol but good to know of the alternatives when the time comes.
I use POTA because it basically is technidol to my understanding, I process it the same way, the results side by side were the same. So far as I could tell.
You can use any developer but you need a low contrast Dev to get the "normal" look from TP.
Sold off all my TP and technidol a few months ago, no time, it's fun but not necessarily usefully consistent as the price of used is high and storage from person to person is different.
Good luck!
For 120 film I have used X-Tol 1+5 or 1+6 (one shot) at 72F for 10 mins (N dev.) in Nikon reel tank using the agitation plan for POTA. I expose at ASA 60, and I get great results.

I've used Caffenol LC and Caffenol LC+C (low contrast versions of Caffenol) for microfilm stocks, including Adox CMS20, which are (relative to contrast and resolution, though not in spectral response) similar to Tech Pan. I prefer the non-staining LC+C version for this application, but it's worth testing both; preferences are very personal.
If a contact print at arm's length is too small to see, you need a bigger camera. :D
