Holger,
There are many answers to your questions. You will have to get more
specific about the wire lengths and the band(s) of operation for
specific answers.
If you want an easy antenna that will work for 40 thru 10 meters with no
feedline, download the KXAT1 manual from Elecraft and look at page 10.
It is just two wires and a BNC to binding post adapter, you can't get
much simpler than that.
If you just want to experiment with antennas, feedlines and matching
networks, do it with some education - get the ARRL Handbook and the ARRL
Antenna Book ans spend some time studying while doing your experiments.

Who knowns? I'm not asking for a *specific* optimization, I'm asking
for a general rule of thumb.
I'm not talking about a permanent installation, I'm talking about going
to some field, or hill. I don't know the band in advance, I don't know
the propagation conditions. And I have several lengths of wire with me,
I can adjust the wire length. And given the circumstances of the
location, even the layout of my wire (only on fiber glass post, between
tree and fiber glass post, etc) will change (e.g. sloper, vertical,
etc). Even the high will be undefined and/or changeable.
That is actually to fun (for me): to change things and try out.
