There may be a generational factor here Marc. How you feel about using a light meter often is influenced by what you learned just starting out. For myself, and perhaps others, we started out just "learning" how to judge light. That was in the early 70's for myself and my mentor had a handheld meter he would consult only occasionally. The proof that his method worked (at least for him) was a strip of 36 Tti-X negs with very even and consistent density, they were easy to print.
Just turned 70 myself and often stuff a Gossen Pilot in my pocket if I'm wandering about outside. that cheap little meter will suffice for daylight and even do incident readings. I personally do not to consult if for every exposure.
Now, exposing photo paper in large format, that is really hard to get right, and a metering of the scene is only a starting point.
As far as wasting film....well I'm also a member of Filmwasters forum and as such authorized to waste film.
