Sander, thanks for posting your negs. They look like several others I have, where the unevenness is more subtle than the ones I posted above. I believe my problem has probably been developing two rolls in a two-roll tank or developing one roll in a one roll tank and taking it too easy on the agitation. With 35mm, I always have an empty reel or two on top of the tank, but not always with 120. I'll follow your advice and that of Bertil. It's odd, everyone kind of agreed on the other thread that it was light leaks, but I believe now that it's a devlpt problem.
