When I was in trois vallées in march, I went very well with my bridge. But it didn't snow since 2 weeks and there wasnt powder at all. The back country was very crusted.
So the question, what ski you should get if you'r skiing in france is, when will you be there? The snow conditions are very differing in the savoie, you won't always have powder.
How long will you be in france and when? If you're going to went there in december or january, I would recommend the kungfujas, you won't need a ski doing well on the pistes, becuase there is no target in france you can't reach through backcountry, even if you're not a pro. If you're there the whole season, buy 2 pair of ski
