I am also starting to explore B&W slides for my stereo Sputnik camera.

A few questions come to mind from the research I've done so far:

1) Are there any fogging redeveloper formulas which can deliver neutral toned slides? All of the formulas I've reviewed end up chocolate or sepia if you use chemicals instead of light for the 2nd development
2) I'm leaning towards a permanganate / bisulfate bleach vs. dichromate. I hear this really softens the emulsion but that colder temperatures can help. Can I slowly cool the film after being washed from the 1st developer before I put it in the bleach? The bleach would be cooled as well. I'm thinking about 55-60F. I would increase the bleach time by about 2x.
3) I'm planning to use HC-110 according to Jordan Wosnick's formula because I like HC-110 and have it handy. Is there a big reason not to do this?
4) I'm planning to use Efke 100 and HP5+ for my films. Again, thoughts?

Thanks! I've learned so much from this group. What an incredible asset to photographer's everywhere.
