I used to use lop whenever I had the chance, which wasn't often, had gamis, UBG16 and it seemed to work as advertised.
Mostly though in my line of work I liked the fuel flow needle to be nudging into the MP side of the gauge, at take off, and also plenty rich in the climb. All my engines (520s), went to TBO with no major problems other than the odd factory AD.
I would fully support Walter and Jabba and co in their lop ideas, for the average pilot, done properly with the right set up and gear it's a no brainer. A lot of people simply can't be bothered, or can't justify the set up costs, and just run plenty of fuel, nothing wrong with that either.
"And btw lop old as so it's not in it ether."
Unless iv'e misread that, I think even hard working engineers, (mechanics) at the coal face may even be having another think on the subject?
