With ULF negatives I shoot them over a light box with a digital camera, one at a time.
That's what I do too but with 4x5 and 8x10 negatives and only the ones that have passed my "this has potential" step.

I have enough years of experience in the darkroom to evaluate without making contact sheets. For me, photo paper is a precious commodity and I'm on a tight budget as my wife keeps reminding me.
