First ride with a friend with our brand new Flysurfer Peak (pink=6m and blue=9m) in Switzerland (not in the Alps, but in low altitude Mountains called Jura, at 1000 meter high).
Difficult wind conditions (irregular and gusty from 4 to 10 knts). For these conditions, you absolutely need the 9m; the 6m can do the job too, but with less power. Sure, in such conditions, you must work the kites a lot, searching for power and pulling on the rear line for quicker turns, but snowkiting with "classical" double skin kites would have been quite impossible (except maybe with big and expensive Flysurfer Speed or other huge kites).
Personnaly, before the Peak, I was exclusively using 3 powerkites (2.5m, 4.5m & 6m) with handles (no handlebar and almost no depower):

First reason is because I have them since a few years and they are still working well (I only do freeride, no jumping or flying); second reason is because I ride at quite low altitude and winds are slower than in the Alps => Powerkites have lot much power for a smaller package than depowerable kites. And time needed to launch is really short (less than 5 minutes from the car to the ride).
In conclusion, I could say that the Peak is the "MISSING LINK" between my difficult-and-sometimes-dangerous-to-handle powerkites and the huge, heavy and expensive depowerable kites, combining the good points of each: small, light and powerful like a powerkite; safe (great depower), easy to ride and wide wind-window like depowerable kites.
For me, Flysurfer's advertisment is not lying: they developped THE kites for freeriding safely for beginners, but also for fun freeriding (and jumping? See LoloBSD) for experts, especially with really slow winds. And this for a reasonable price, regarding the R&D done.
