Too many good points to comment on all of them, Michael.
But I'll add this about the slaved HSI...
If it also includes an ADF pointer, you'd wonder why anyone
would ever complain about NDB approaches.
You just make the raspberry-colored RMI arrow line up with
the Final Approach Course on the HSI, and then keep it there.

(I'm sure some RMI pointers aren't raspberry, but mine is.)

(I know....."Who cares about ADF?" Well, I kept mine.)

Nice to have. Not particularly important unless your scan is poor or
things happen very, very fast.
