True enough. But, the bit of extra stuff earlier on is none the less
easier and I don't have to worry about making sure I am where I am
supposed to be if I "activate."

And if you have to change approaches, which sometimes happens, you can't
select a new one without a destination airport.

It is rare to fly the full approach in a TRACON environment. But, if it
is a single approach in each direction, you will usually still know
early on. If it is a major airport then all bets are off, so I would
wait until the vectors begin, then do it your way, but with VTF.

However, if the airport has runway specific STARs, then there is another
level of complexity, which can easily overwhelm single-pilot operations.
