........fly a raw data approach out of 20'000 ft from time to time.
Are you realy sure about that? I see no big challange in flying from 20K to the FAF with zero power. If it means intermittendly level offs, means lots of traffic I would consider this rather irresponsible. Besides you put a lot of stress on to your fellow pilot with no real benefits to gain.
In my last company we had 4 Sims every year, so if one wanted to sharpen ones handling skills, there we had plenty of opportunities.
Although I would agree in flying manual approaches given the right parameters (airport, weather, traffic etc) to do so.
