Irina_you look awesome :) what skis are you riding? Crystal changed their set up, no more demo center :( but will try longer skis!
In the gifs I'm skiing 176 Volkl Two's, which Volkl stopped making, but I'm happy to say will be bringing back next year. I think they renamed them the Volkl Revolt 124. As the new name implies they are 124 underfoot so I wouldn't recommend them as a one quiver ski. If you can somehow manage to get a second ski into your quiver I definitely recommend the Volkl two as a pow ski. I can't say enough good things about them, great in the trees, and pretty strong in chop and crud too, which is great since I end up riding a lot of that after everything gets tracked. Surfy yet still stable charging fast.
One of the things I think I failed to emphasize is how much rocker profile really effects how long the ski feels and how maneuverable it is. A full rocker ski is unique in that you can pivot your turns, that's one of the things that makes it great in trees, and surprisingly decent in moguls. Being able to pivot the ski directly underfoot, instead of driving through the whole length of the ski to make your turn is a game changer. Plus I just love how much more surfy it feels to ride full rocker in pow, it planes on the snow better, whereas I'll sometimes ride my Rossi Slats in pow and I can feel the camber zone adding drag. Camber is great in the park and on groomers, adding pop and power in and out of turns, but I hate it for big mountain skiing. If you can get a nice mellow full rocker like what Volkl often does where it's nearly flat, then you can get the best of both worlds where you can still carve a good full edge on groomers but you'll also get that surfy feel in pow. I think it works especially well for lighter skiers like us too, because you don't have to wait for your body weight to depress the camber zone before you can start initiating the turn. The ski is just already ready and waiting preloaded into it's turn shape, makes it feel faster from turn to turn.
It looks like you just missed the Spring fling demo that Sturtevants does every year. You should try and catch it next year, it's a good one for testing out all sorts of skis. I think the only other demo event is the one that K2 does sometimes in early winter for shejumps.
