HC and BROM I strongly agree with your posts re standardisation. In my experience HC is correct that even multiple options of needle displays can lead to confusion.
However, I also feel we should embrace multiple SOPs for differing scenarios especially with the situational awareness tools available on modern displays.
Grenville. You may have a point in the SPH environment but I think most MPH crews on this forum rely on standardisation as a key component of CRM and inherent safety. Not to say we should not tailor anything for a specific set of circumstances but this would always be briefed out as "non standard" to ensure our stick buddy remains in the loop to watch our your back.
I believe, in the MPH environment, two pilots doing their own thing is far worse than one pilot on his own.
