Coming back to this thread one last time now that I've gotten a few days under my belt on the Ripstick 88s. They have really made a big difference in my skiing. I know that equipment can't make up for lack of technique and I have PLENTY of work to do, but I feel like I'm so much better set up to succeed on progressing with the skills I've been working so hard on this year. Both my husband (who is a lifetime skier) and my daughter's instructor (who I did a lesson with myself once upon a time last year) commented on the significant improvement in my skiing these last few times out together -- so I don't think it's just a placebo effect!
The increased stability is decreasing my impulse to rush my turns, and I feel more confident picking up a bit of speed. And more speed is even just POSSIBLE -- on my old skis, one of the things I noticed at the women's clinic was that even when we were all just cruising with skis pointed downhill, no turning to mitigate speed, I was just soooooo much slower than everyone else.
I had a very proud moment on what passes for a black diamond on our miniscule hill yesterday where I was traversing across in some chop and my inside ski took a big, unexpected bump. Even though my inside knee practically bounced up to my chest, I had my weight on the outside ski and forward enough to roll with it and stay totally on track -- that would not have been possible a year ago, I don't think. So, yay for progress and yay for demoing and yay for not being overly influenced by ski shop dudes who were very skeptical than I really wanted a 172 cm ski, because now I have a much better tool for the job and it's awesome!
