My comments are a little late comming, but I'll contribute my thoughts on APX100 and Microdol-X 1:3.(posted 8205 days ago)I fumbled across this combination quite by accident. I haven't done any formal tests, but for my work, it is THE perfect film/devloper combination.
I soup at 70C for 20 minutes with a two minute presoak. Continious agitation for the first minute, then 3 tank inversions (about 5 seconds) every 30 seconds for 0:30 to 10:00, then I back right off to 3 tank inversions every minute from 10:00 to 20:00. Water stop and fix as usual.
