The 15cm consists of:
- about 7cm comes from my old back lines being about 7cm short. I would consider that normal on a well used set of lines. The new lines set is all same length. That will change over time.
- 8cm being the difference between the end of the chicken loop in the harness hook and the end of the release on the Pintxo bar tied on the top of the harness hook but closer to the spreader. That is fixed and you have to do something to change it.

It's easy to change the position of the bar. Choose your method and do it. (change the line or pigtail settings, change how the bar is connected to the harness, ride in stronger winds, use a bigger kite)

The point I think I have made in a number of posts is a) the bar is different, and b) you can adapt yourself to it, or c) adapt it to you.

How's the Teflon tubing performing vs the PU? You forgot to follow up on this, but I'm sure you've been busy
When we made the tests it was pretty quickly clear that PTFE (Teflon) is much better than PU tubes for our use. Especially at hot temperatures like we had Spain in summer the PTFE tube worked way better. Beside that it slides much smoother through the bar hole. The only thing that you have to take care of is, that you do not kink this PTFE tube. When you put the bar into your bag you always have to take care of that. It`s not a big thing and I am really happy now as the tube lasts way longer. I was in touch with plastics institute of the university of Aachen in Germany which is my home town. They have also advised me to use PTFE.
Anyway thanks for your advise, too. :D
Did you check ETFE? It is more flexible than PTFE and PFA, and more resistant to kinking.
But probably more expensive too.

Not yet, but I will definitely do. On the other hand I am not so unhappy with a little bit stiffer depower rope and our customers reviews are confirming that. The PU tube was very flexible and the new PTFE tube feels more solid and durable. I keep on working and testing nearly every day on new materials. I keep you updated in case there is a need to change anything at the current setup.

Thanks

Ciao
