with all due respect, there are not lots of opinions at all.
There always seems to be facts and evidence based operations, and OWT's.
As for a thread on LOP v ROP
that will degenerate for sure, but let me say this, the lower case v in a title suggests one is opposed to the other, like Qld v NSW in a sport. One is opposed to the other scoring more points.
LOP is not opposed to ROP. ROP operations are perfectly valid and safe to do so provided they are conducted properly. Same for LOP ops. Heck ALL my takeoff and climbs are done ROP, and once climbing into the upper levels you are chasing best power and using a ROP setting that would not be wise at sea level. I often use ROP above 10'000. LOP is just more fuel efficient and kinder on your engine than running 100-200 ROP for not much speed loss.
Grasshopper you have much learning ahead of you!
