I think all it comes to personal preferences, the way you look after your equipment, and what are you used to.
It may be the best quality kite in the world, if you trash it, don't look after, it will go "kaboom" in no time.
So I don't see any reason to start again a long controversy here.
Wilbur, if you feel you like Airush, if it feels good and you enjoy the kite, this is what's important.
Any way, almost everybody I know in the sport updates the equipment every second year, so.... good luck with your choice.
