I have a 2014 17m Contra. Last May I stretched out the bungee on the trim tab line that is on the over drive bar. I didn't get around to fixing it until September. It turned out to be more of a pain then I imagined but I think I did everything properly.
Since then I've only ridden it twice. Once in September in light wind and then I had it up yesterday in higher winds. I've noticed several differences that have me a little perplexed. First the depower seems to have drastically more throw. Second the control spring that pushes up against the stopper ball seems to fully compress much more frequently (a result of having more depower throw). Third the kite itself appears to back stall and look over sheeted regularly. The first time I rode in September I thought light flukey wind was culprit however after today in much stronger winds (18-20) I tend to think I may have not properly reassembled the bar setup after fixing the trim tab or have an issue with the lines. Back stalling led me to check the line lengths this afternoon. I found a knot on a center line just below where the stitching starts before forming a loop at the end of the line. I'll chalk that up to rushing when setting up but I doubt one knot would cause such a noticeable difference?
I followed the videos on youtube and it appears that my line lengths are not even and need work.(see photo 1). Is this much stretch in the lines common for less then two years of riding?

I adjusted the figure eight stopper knots on the steering lines but did not get as much of a change as I was hoping for (see photo 2).

It does not appear I have a lot of room to move the figure eight knots much further. Would I have to shorten the middle lines instead to compensate for not having more line on the steering lines?

I've only been riding for a little over a year and half. The first 5 months were mostly on the Contra until I moved. Since then I have been riding a 12m and 9m bandit 3/4 of time. I'm a bit surprised/disappointed with my Cabrinha experience thus far. I could understand this happening if I was riding this kite 24/7, but that is not the case. Has anyone had similar issues or have any advice? What is the average life a set of Cabrinha lines? Thanks for the thoughts.
