Hey Bert77,
If the Pansh comes with flying lines and handles then it must be a 4 line, not a 2 line. Handles are pointless without brake lines.
If it does come with 4 lines, you can tie the two rear lines together and to a piece of bungee in the form of a big "Y". Then attach a wrist leash to the back lines via the bungee. This will give you a wicked safety kite killer where when you drop the bar (Broomstick) the kite will collapse and plummet powerlessly trailing edge first into an inert heap on the ground. Obviously, the two front lines are attached either end of the broomstick.
In fact if you wanted to do it properly remove one of the back lines and add a "Y" piece at the top of the line and attach the two ends to the two rear line bridles, this will help reduce stalling and help the kite fly a bit faster and further upwind in neutral due to less wind resistance against the 4th line.
Do not use a wrist leash on the front lines of a foil kite unless you want the kite to pinwheel until the lines are so twisted they resemble rope.
Good winds,
