jensmadwind, not to "take anyone side" , but why one decision to use a leash Vs 'work a bit hard' on body dragging is so wrong ??....
There is no law that you cannot use a board leash...
and there is no law that says you must have common sense either.
But there is NO NEED to use a board leash. If you are kiting at some spot/or in conditions where you feel a leash is necessary than you probably should not be kiting that day. The risks of a board leash under those circumstances outweighs any other options IMO.
Every single one of my students, in over 500 lessons, learned how to body drag and retrieve the board. It's no big deal to learn the proper technique.
Yes, it is hard to find a twin tip sometimes in big waves/choppy water. But using a leash on a twin tip is like tieing one end of a rubber band to your body and the other end to the handle of a machete...very risky.
A surfboard will float higher and will surf it's way downwind quickly, sometimes all the way to the beach before you catch it...OK, minor hassle in comparison to getting your teeth knocked out because of a leash.
If you follow the cardinal rules about what conditions are safe for kiting your board will end up on the beach. It's always nice if another rider can assist if you get yanked downwind and saves you a lot of dragging. Put your name/tel/email on your board just in case you can't retrieve it.

or buy a Go-Joe from OCean Rodeo. A lot cheaper than the Energency Room.
