Very comprehensive explanation ! Thank you !
The method with the screw is a really good. I have seen this in the Rostock Mini Pro build.
I used 2 component glue. Breaking stress at approx. 1900N/cm² as the manual says. Cutting the rods at the ball joints and attaching a set screw would be best practise but on the other hand I could get new ball joints and carbon rods with the same inner diameter. I think the ones I have right now differ (carbon rods ID is 2.5 mm, ball joints are 3.5mm). So I could use a m3 set screw to connect the ball joints and the carbon rods.
The outcome would look nicer than the cut black plastic pieces from the ball joints :)

Thanks Wildcard !

PS.:
To get the ball joints perfectly parallel on both ends of the rod I did following (see attachment)
