Think Sandmand said to make them Shorter to depower???

Hey dude, maybe have another look at the manual. If you make the centre lines longer this means the back lines are shorter in comparison. So think about when you suck the bar in, it shortens the back lines making the kite power up.
So by making the front lines longer you power up the kite. By making the front lines shorter you depower the kite.
Then vica versa.
I always try to teach people about the bar end and then make them see the connection on the kite.
So basic rules are back lines are power lines. If you shorten them the kite is powered up. Same as sucking bar in.
If you adjust front lines think about what they do to the back lines and you will have you answer to power.
Bennie the oversheeting thing is correct but that is because your back lines are too tight and the kite too powered up.
