Foma Home Reversal Kit vs DR5

The issue here seems that CD-x is a Kodak designation and member dE fENDER used it as a generic designation in combination with ordinal-numbers from designations of east-european developing agents.

CD-32 likely is T-32 (p-[N-Ethyl-N-hydroxyethylamino]-anilin)

Seems that CD1 and CD8 are the same except for the form of the salt. One is the Sulfate and the other is the Hydrochloride.

Ive a good recipe for R100 on here somewhere, and the best looking slides Ive done generally are re-developed with catechol and sodium carbonate A and B mixed together prior right to use, then followed up by any regular re-developer before fixing. Which gives a particularly high dmax, pleasing look with readily available chemicals.

Would it be this Resource of yours that I posted on page 2 of this thread?

By the way, I do intend to follow your instructions on a roll of Fomapan R100 stills as practice for doing a roll of double-8. Not ready to do it yet, though.

Truzi, I can vouch for Athril's resource on Fomapan R100 reversal processing that you linked above. I use it when I develop regular 8mm fiilm and it comes out great -- thanks, Athril!

As for DR5, I've never personally used them, but I've seen slides developed by them and I am very impressed. Excellent DMax. From what David Wood has shared of his process, it differs from conventional reversal processing in some significant ways, but obviously, he hasn't given away all his secrets.

I wish I had a better understanding of reversal processing - I've read all the literature I can get my hands on (Haist V2 being the best.) For some reason that I do not understand, it seems like the recommended D-67 is not suitable for many films.
Using D-67 I've had success with:
- Ilford Delta 100 (15 min at 20 °C; gamma = 2.7; DMax = 3.5; DMin = 0.3)
- Rollei superpan 200 (6 min at 20 °C; gamma = 2.6; DMax = 2.8, DMin = 0.1)

After a fair bit of testing, I cannot find satisfactory results for: TMAX 100, TMAX 400, Delta 400, PanF+. This is using D-67 and varying the time. I got tired of testing, but someday I'll pick it back up and try to find a good process using a different developer.
