I have the ski cross 9, 178 length (6' 240)...I believe the 03 model? I really like it, but don't have much experience with other skis to give you a comparison. I'm using marker bindings. When I purchased them the salesman told me the big difference between the 9 and 10 is that the 10 requires specific bindings, but the 9 will accept any. I had just purchased the markers a year or so earlier and really didn't want to buy another set of bindings, especially since I was still in college and on a tight budget.
I've only had it on groomers, ice, and very very light powder. It carves very smooth and confident arcs. The first time I skied it I was amazed with how well it turned, but part of that is probably due to my prior skis being K2 twos.
The only other skis I have are some 168 Fischer slalom skis I bought used at the end of last season. They turn a lot sharper and quicker, but are a lot less stable at speed. After a day on the Fischers, the Dynastars are very relaxing and easy going.
