It is sensitive to agitation and contrast will go skyhigh if you dont watch out. For Technidol I rate it at 25 ASA and I have been playing around with a formula that gives 200 ASA. It seems to work but I am still looking for some missing zones in it and once I get it working properly I let you know. The tech-Pan does not like high contrast subjects that much, it is inherently contrasty as it is, but with only 25 asa on "tap" one tends to shoot in bright sunlight and swear in the darkroom instead. Great film when it works, absolutely miserable when you blow it! I have tried some with Rodinal too. Rate it at 12 ASA ( no misprint 12 asa) and develop in Rodinal for 12 minutes with a dilution of 1 part Rodinal and 300 parts water. Works fine. It is a film that is very exposure sensitive, shoot it like a Kodachrome 25, it has about the same forgiveness for under ( less than 1/2 stop) and overexposure ( no tolerance at all!!!), but when you hit it right it is incredible. No grain and smooth tones. Only way to deal with it is to adapt it to your own shooting style and be very consistent with processing. Let me know how it works out and when I get some of my Tech Pan formulas that I have been given, tested and tried out I will let you know about them. You will also know to no uncertain degree wether you are in focus and how good your lenses are. Remember too that Tech Pan has an extended redsensitivity and this can fool you if you use filters.
