IBW2, sorry I'm actually helping as much as you did. You simply posted a link with a Cab advertising video and told JTBird he has no excuse for not having untwisted the lines. I'm telling him to try a different brand, that's all.
Correct. One of the posts i sent to JTBird was a video which clearly showed how to untwist his lines. He said he had a 2012 Cabrinha kite and was complaining that he couldnt untwist the center lines which seemed very strange as the 2012 system makes it extremely easy to adjust center lines. In addition to explaining how to untwist the center lines I also thought that sending a video would be good. JTBird has now corrected his post to say that it is not a 2012 Cabrinha system but a 2011 system.
I have been involved in many many self rescues and self lands (well over 100) since the introduction of the IDS in 2009 in winds range from 10-40+kts and have never experienced any issues that JTBird is describing. Therefore my first instinct is that he is doing something wrong and maybe can tweak his technique so to ensure everything goes as should be. I for the most part fly the Cabrinha Switchblades and 9.9/10 they will end up on their leading edge down when releasing the QR1 onto the IDS line. In the rare case when releasing the QR1 do they fly on their back, and this is still never an issue as the self rescue and self land process is still the same ie being very easy and controled. In the event the user does not do the self land and self rescue process correctly and cause the kite to power up , the user has the option of releasing the kite instantly.
What move are you throwing only in one direction? It does sound like you are spinning so many times in only one direction that now when it comes to releasing your safety the iDS line wont slide. This will be the case for any system whether it be 5th line, single front line or IDS type system.
This method of untwisting your front lines might help. If you have access to a shallow area which is safe enough away from danger, gently rest your kite down on the edge of the window. Put both hands on the chickenloop, unhook and twist the chickenloop until your center lines are back untwisted. Hook back in and off you go again. You can do this method in deep water, however, best practised in the shallow water first.
I am tempted to do a test using the Cabrinha Switchblade using the 2011 lines and seeing how many twists of the center lines will be needed to stop the IDS line from working. My guess it has to be well over 10 twists which would mean for example, ten back rolls in only one direction The twisting issue is really only an issue ever for intermediate riders that are learning to front roll, back roll, kite loop, downloop in only one direction. Beginners are learning to ride and advanced riders will spin in both direction in at least one move if not all, thus never having many center line twists.
The minute i finish a kite session, I will always ensure my center lines are not twisted, so that walking out the lines for the next session is a breeze.
