Here's another "habit" shared by some skaters that I find very unattractive -- wrapping one leg while rotating for jumps instead of pulling both legs together.
Midori Ito typically wrapped one of her legs during many of her jumps, and while she usually landed the jumps successfully - she was a phenemonal jumper (!!) - that wrapped leg was very distracting, IMHO.
I just think this is an example of poor technique. I can't imagine why a coach would not correct this habit when the skater was just learning the jumps. I recall seeing a tape of Midori as a five-year-old, rotating single and double jumps and wrapping her leg in the process. Obviously, this was a longstanding habit, and perhaps it was one that was impossible to break.
