Dewdrop,
I take the view that a flight that I fail to learn something from is a wasted flight. It probably also signifies complacency, which if I ever feel I have developed, I will STOP - I want to stay alive.
I have never failed to learn something when flying with an instructor, and even if it is a check, will make sure that we do something that I am not happy with, or something new.
So if your new instructor insists on a check, then see what else you can get from the flight.
