It is your own fault, when you wait so long with release the kite. No system is working with lines twisted around after some loops. It happens to few time a year I have to release the kite totally, when the safty leash goes around the bar missing when missing a air pass. Be happy you are not a virgi...
September always rocks. Nothing to worry about. For 4 $ a moto will take you to la boca.
( the flatwater spot. But it is very small, so I recomend the ocean )
Forget the Evo. It is such a slow borring beginer kite. The Rebel is world class, and great for waves because it is fast. It will not pull you away from the waves like the Evo.
