Reading negs is nice,
but often one or two contacts on the roll will surprize me with results I didn't expect.
Cataloging is much easier for me with contact sheets from each roll.
Some of my sporting photos are offered for sale directly to the competitors by letting them sift through the contacts from earlier competitions with a magnifying glass and loupe. Works best when I had the same EV to use throughout the roll, obviously.
I used to, but now I've started scanning the negs and printing out contact sheets on a budget printer. I feel dirty doing it, but my time in the darkroom is so precious now, at least I can get this chore done up front.
