I use pretty new enlarging lenses (including the last production of 63mm El Nikkor) for my negs shot with older lenses in various types (mostly Canon NFD and some non-Ai Nikkor lenses), and I like this combination. I get pretty straight results from the negs.
And for some reason, even when I neg-scan with my Nikon scanner, I don't see much difference in the look of these images on the computer screen. So I don't go too far off either way, and I can prepare the materials and the setting before going to print in the darkroom.
I do a lot of brain-storming outside of the darkroom, and I like the quality of what 35mm negs produce. But what affects the final look also depends on the type of chemicals and the quality of paper. So, I try to stay as flexible as I can.
