I got the Sierras mounted (with Look Pivot 12s) and took them out today - conditions are rapidly deteriorating so this is my last day of the season. I'm not much of a spring skier, and the snow was either super hard and icy or super slushy with tons of exposed rocks, so I stuck to the groomers. I feel like I need a few more days of skiing in different conditions to really get a feel for the Sierras, but here are my initial impressions:
* I thought they would be unwieldy and hard to turn as they are wider and longer than any other ski I've tried: they are actually super nimble, they feel shorter than my Sheeva 9s (that are 164), and I had no problem doing pivot slips, falling leaves, or flat 360 turns. I feel like they would be great in the bumps and trees. They also feel wayyyyy lighter than my other skis and I was much less tired at the end of the day.
* I thought the triple camber might feel weird or throw me off: to be fair, I don't think I did any real carving today in these conditions, but I never felt like the tails were grabby and never caught an edge. I could release from any turn.
* Wasn't sure how the center mount would feel: honestly, they feel great! The Sheevas really reward being forward on the skis and driving hard, and it was nice to ski a little more relaxed - and again, it was much less tiring.
* I couldn't get on edge at all on the hardpack and my first few runs I felt like a newborn deer. I was able to feel a little more comfortable once things softened up, but I think I need more practice in normal conditions to figure out how to carve these things.
Definitely looking forward to skiing them more next season - I have a really good feeling about them and think I've found my skis!
