Just an update, I am putting more work into making 12x16in prints - which I think will become my "regular" size for 6x7cm negatives. I bought a big box of paper, and a lovely Schneider W.A. Componon 80/5.6 enlarging lens, which appears to be phenomenally good after a couple of test prints.

Does anybody have experience with the W.A. Componon? Some people snub "wide angle" enlarging lenses (it covers 6x9cm) but I figure I am using only the "good" part of the lens anyway, even if it had vignetting softness in the corners. However, I doubt that this lens is anything but perfect based on my experimentation, certainly for anything up to 16x20in in anyway.
