Whaddo I know:
If you're not over 6' (183cm) tall or too broad, buy P7. It meets
all your listed requirements.
Don't expect to accomplish everything it's seller has done in the
Ventus, most of us can't figure out how he does it.

However I think that the automatic control hookup thing is a little
overrated.
....As the crowd are loading rifles, I can say I've had a L'Hotellier
fail in flight, and landed safely.
It was an LS-6a with the LS sleeves in place. The spring in the
L'Hotellier failed.

If pilots don't want to be responsible for a proper preflight and
positive control check (also known as a D.I.), there are other things
are likely botched up. For example, it's possible to launch a few
gliders with the MAIN SPAR PIN missing! That could spoil your day.

My next launch will be in a glider with ten control hookups I am
responsible to connect (six with Wedekind sleeves, four with attached
safety pins), plus three spar pins to install and safety. The glider
cost half what the newer one with automatic connections would have
been, and according to some pilots who have owned both, has similar
performance.
