In the interests of "fewer parts, fewer failures" and single-handed
(literally) portability, I'd be hard- pressed to come up with an example of
a full- blown overflow setup that's as easy to transfer and set up as "hang
and suck".

I don't believe I questioned the comparison in techniques, only the
complexity of its application. Nor have I any problems comprehending the
mechanics - I would have clarified that if I'd known such was hidden within
the generality of your original question.

By this roundabout statement I'm assuming that you mean there shouldn't be a
difference between a sump setup and the self-leveling siphon (rather than
hinging on _position_ as the statement infers).

So far, for the sump setup, you've mentioned:

at least three required parts. Unless, of course, you're using an internal
skimmer/overflow, in which case you now only need it and the lower lever
supply hose.

Mine you can grab with one hand - even maintaining its fill (thumb over the
tank end) - and move down an entire row of tanks during water changes. Just
"hang and forget" at that point (and no - skimming is definitely not
included. But then again, it's not the intended function of the system,
