Tested my a15 in 9m2 on soft snow (main application in my case) ; very happy with it .
Stability is really really good even in mountains; you benefit from closed cells structure and it seemd more stable than the Ozone open cell from a friend (rapid feeling to be confirmed) . Agility is enough to climb up mountains ; I would have dreamed of shorter radius without pulling hard on the bar but it is acceptable, far better than Lotus S4 10m but not so good as Concept'air Pulsion.
Launch and relaunch were really safe in this wind range, and I have been able to relaunch several times in all 'funny' kite initial positions. Depower is not wonderfull but I was able to ride comfortably in 4-16 knots (26-28 m lines are still a bit long for this 9m2).
Wind was too low overlall to test proper jumps, but hangtime seems medium I would say (which can be an advantage in snow). I tested my first tacks on ski and it was so great with the a15 that it became the main theme of the day
. : with / without speed, with / without loop, with / without unvoluntary backward jumps , with my ski trace never re-crosssing itself (like air tack on foil, upwind only), etc ...
Light cloth is not mandatory but it was very comfortable even in 9m2 in 4-5 knots lulls to keep the kite in the air waiting for the next gust.
This is a very good deal for that price IMO.
