The fomulary kit is optimized for the tmax100 film, however you could likely do better making it up yourself.
None of the kits provide a satisfactory fogging developer.
Grant Haist has made suggestions on fogging developers but should be modified for each use.
I would not suggest permanganate bleach. Not only is this agent explosive, it does not provide the best image quality. Sulfuric acid concentrations should be reagent grade - 96 - 13ml per liter [cant figure the % off the top of my head] for bleach. You should also use Di water as well. The bleach will leave deposits on the film if you use poor quality water, bleach agent or Sulfuric.
Dithionite does nothing to help the reversal process, its not even worth trying.
The best film for doing interpositives is infact tmax100. It is best shot @ 40iso for this use, to make interpositives. EFKE50 is also a very good film for this use but only in a chemical reverse.
Rodinal, if it has p-amimo hydrochloride in it [the new version i think does not] is actually a very good agent to use in reversal processing, a very nice image quality but very expensive.
