May I ask why you found the shutter so important?
Controlling consistent exposures using the enlarger timer at <1 second can be a problem, even with a pre-warmed bulb. Even Ortho at ISO 40-80 is significantly faster than paper. With a shutter I can start with the bulb on. Since I have the LF lenses, and I find it makes things easier, that's how I do it when the need arises. I could reduce the light output and try to stay in reasonable reciprocity correction levels. I'm just lazy 8-)

Thanks, that does clear out a few things. I looked up the 2 films I want to use; one has a reciprocity failure past 10 sec, the other past 128sec. So, I guess I'll try to go the enlarger way, with a 80A and a 1 or 2 stop neutral density, wich would bring the neg to an ISO 10 or 20. This should give me a manageable exposure time that might be more consistent. If this doesn't work, then it's pinhole construction time for me!
Thank you all for your help!
