Interesting thing happened to me this weekend. I intentionally left my poles behind. Carrying my 4-year-old's skis, helmet etc makes it really hard to carry poles as well.
At first it was really really hard. I just couldn't ski. So I PRETENDED that I had them. Making the pole plant motion with my arms was perfectly fine.
As I carried on, without the focus of pole plants, my brain gradually started to think of skiing as a single fluid motion, and not a succession of turns around pole plants. Within 30 minutes I was carving in a dynamic style! I was on a very groomed black run (red dog at squaw). I could feel the edges, the speed, and I had pretty decent angle, and I was keeping pace with the race kids. I really thought I could never ski like this, but there you go.
Drop your poles. (worked for me, ymmv :D)
