Z-lines are brakes. If you have them too tight bar pressure increases a lot and kite stops when fully sheeted in and kite backstalls. Sheeting out kite flies fast, in general behavior of kite becomes twitchy.
To name this kind of setup some kind of camber adjustment is too simplistic.
There should always be some method to adjust brake tension, because it is quite a lot personal choice how kiter wants them. But if you look how well tuned efficient kite flies you won't see almost at all brakes working. That is because if they do (considerably) kite gets slower. In very low winds most essential is to get foil kite flying as fast as possible.
Even better if brake adjustment can be made separately between center and wingtips.
I remember years ago first test flight of a kite in which I had much too long brake adjustment line resulting brakes were slack all the time. However kite flied well and also looping was possible. Only real advantage of very tight brakes is downwind use or trying to make slow kite reacting a bit faster.

Been looking at the FS Speed5 line plan. Obvious immediately that the Pansh Aurora II has a connection from Z to C through "C7". The Speed5 does not have this connection. Anyone tried eliminating that ZC connection on a Pansh. Maybe that has some cause of the sensitivity to backstalling. Admittedly a foil newbie but seems a major difference!
It is useful, because wingtip LE is already pulled 1:2. If you fix c7 there will be upward bulge in the middle of the wingtip. Drawback of that line is when it rolls through the ring it shrinks. Reasons of backstalling are much more fundamental than a single line in a wingtip.
