First of, I used 3 m of 6 mm pure dyneema rope. This means that at full power the whole system is just 1,5 m long. From the first ride this seams to be a bit short realy. When I depowered the steelring got so close to the bar that it effectively hindered any movement of the bar. So, experienced learnd is make the system looong and use long leader lines on the back lines accordingly. Further the use of three steel rings makes the system very hard to move under heavy load because of the friction. I´m now switching to at least one pulley at the top just as the zeeko original. Does anyone know if zeeko us a pulley at the chickenloop or just friction via steel ring? Would the system still work as intended if I use pulley at the chickenloop?
I also made setup using a tab with a prussic knot. I mad one red and on blue, for power de-power. Leasson learned is tha you realy need to have them connected (i did not) since when you pull the de-power down the other one moves away up the system and out of reach! OR if pulleys are used only one tab is needed to both pull and push. My system was impossible to push unless I whent downwind to reduce the forces on the system!!!

Question! Without a hard stopper somewhere wouldn't you risk loosing the bar (i.e. getting pushed out of reach, especially if powered (ring furtherst away from body).
