If it's a "lesser image", I don't think it's worth printing. Why spend the time on a negative that won't give you a worthy print?

I do think it's a good exercise to go back to old negatives, from time to time, though. If you've been at this for awhile (in my case about 40 years), you'll definitely discover good images which were difficult to print. As your printing skills improve, those old negatives may yield nice prints which your early skills couldn't coax out of the negative. When I first started, I knew nothing about flashing, split grade, and had rudimentary dodging/burning skills. As I acquired those skills, negatives I had passed on became easily printable.
