It can only pull the depower strap to your bar... it just takes twice as much rope to do it because of the 2:1 advantage. The kite doesn't flag. It keeps flying.

The "safety" on a waroo is it's 90% depower. When you let go of the bar, that's the safety UNLESS you connect the leash to one of the outside lines in which case you have 98% depower and the kite is killed (well, spinning on one line anyway).

Using the chicken loop safety is effectively a "suicide leash" but with an automatically releasing stopper mechanism.

In 90% of the cases it is sufficient... but if the kite is looping or you are getting lofted you are screwed. Your only option is to ditch the kite.

FWIW this is why so many waroos got released the other day when it went from 15 to 35 ... really there is no other option but to ditch the kite (unless you connected to an outside line).
