Hi everybody and thanks for the interest,
I was surprised myself that even the high AR (think about AR 7) old "Aspect 3.0" wing now worked pretty well, as I tried it an year ago and thought it is just to hard.
I was thinking and discussing about ideal monowings with people like kite designers, not being noobs like my in hydrodynamic. But on the end the result was always:
big low AR wings as for example the levitaz cruizer, which is the easiest I know. All other ideas as sweeped back wings or high offset towards wing tips, can be helpful for normal airplanes, paragliders, kites ... but potentialy have no relevant effect if balance point is not about 1 time below wing span as on paragliders, but about 4 times above wing!
So there is maybe just human brains regulation capability and processor speed to count on
AND, not to forget: to make the situation for its bodies and muscles as compfortable as possible:
Stance and AoA:
AoA is not changeable for Levitaz system, but an pretty important point. First my stance is with mono strut full in front, front screw of back strap directly over struts trailing edge, with moderate stance. With stabi strut about 3 cm more to the back which should be roundabout the compensation of pressure point movement with and without stabi. Just finding this and maybe a bit experience enlarged my regular speed range significant, as if you compare this one with now often above 30 km/h with older tracks shown
Track was first 8 km upwind than about 15 km downwind, than upwind again and freestyle on the end, see track picture at:

But even more important is to have a angle of actually calculating with 3 degrees set not inbetween wing and strut, but inbetween stance (upper deck) and boards lower deck, as also today I see many racers use it for a more compfortable riding position respecting balanced load through both legs under high load. While my load is normaly not so high, it is even more important to have both legs close to straight in the most challenging "high speed" moments at around 33 km/h to be able to push this limit further.
About lowering drag and low wind planning limit:
I believe that I was even able to feel the difference of the new reinforced levitaz strut bases-wing-connection compared to the old with smaller frontal area (around 1 cm² difference maybe), why I kept the old weaker struts. The experience with my old race foil, I was riding with fun for two days, once again was like: Oh, it is so more draggy and needs so much more kite power to get going and difficutly to reach high angles against the wind in the low end. ... But I don't have any real numbers to show, just a few tracks with high upwind angles which may show that it is not just a feeling.
But to maybe get clear values, I have set up this topic to ask for them, if somebody else can give it to us:
