A nightmare for every kiter is a broken line. To make things worse it happens often right in the middle of a perfect session. Then the next step is thinking of a solution; buy the same lines or maybe look for an alternative?
Better to prevent than to cure
Probably the best way to prevent any breaking lines is investigating some time in what bar and lines you are using.
Which lines are the best?
One of the most important facts on a bar is the strength of the lines. A stronger line usually also means a thicker line. Thicker lines means more drag, so a stronger line will be beneficial for the durability but may also affect the flying aspects of the kite.
