I agree with you. It's best to operate the aircraft exactly like the manufacturer intended for it to be operated.
Another procedure our company wants us to employ is to limit the ITTs in the climb to 740 c max. This is all good and well but it often means our actual torque is lower than the pointers of the FDAU torque bugs. This means the aircraft takes longer to climb to the cruise altitude at a higher operating temperature which in my view, adds more wear and tear over time than to just climb at the torque the FDAU bugs "suggest".
