I have to agree with shawn...
a lot of us are very impressed by the technical tricks of the pkra because we know what they are and can relate to how hard they and how it must feel to land one... h
ow ever, when I think back ( i think it is the same for most people here) to the first time I saw kiteboarding about 3 years ago what stood out the most was the fact that you could pretty much fly with one of the those kites, I hardly remembered the low-kite tricks... and like shawn said air is were the attraction is... when people see me kite the only thing they want to see me do is a big jump... it's what sets us apart from the others, racing, wakestyle, cross, etc... can all be done in other sports, but getting launched from the ground like a rocket is our domain, unless you work for nasa or in a circus...
events bring in the public, air ignites the fire and attract new riders, which brings money, new companies, better and cheaper gear, and more friends to play with...
I personally like the kpwt because it promotes variety in the tricks, and even though the riders can all pull crazy handle passes, it's when they are forty feet of the ground that the crowd goes wild... to bad they can't get more riders to follow the tour....
