Well i have a 12 Alliance, have had now for 2 months & out almost every arvo.
So, the shaped is awesome, amazing depower, I'm a little under 70kgs on a 132 board & happy out in 30knt winds & can stay up wind just in about 16-17knts
As for the kite.....
Nice one pump inflation system, easy self launch & self land.
2 weeks old, the bladder started leaking around the valve (replaced under warranty no issues thanks to RPS
I had the demo kite out whilst mine was being repaired, now i'm pretty aware of the usage of the kite as the majoritity of it has been myself. It has had maybe 6-8weeks use max.
I was midway through a backroll & kiteloop when the front main line snapped on me the big 5mm one, And i make sure that lines are clean from sand etc, when packed away.
So not sure if that has something to do with the rope being used or what?
But otherwise... awesome kite!
The alliance isn't as easy to water relaunch as it needs to be pulled onto its back with the 5th line & then swung around to relaunch so a bit harder, but moral to the story is don't drop it

Would i buy another? The answer is yes! the Alliance just works, the lack of grunt you might call it was odd at first but have since worked out how to get more pull out of it
Probably go a 10m next time and should still be good in 18 - 35 knts
Cheers
Andrew
