I had the stealths. I treated the edges pretty rough skiing on pavement, brick and had no problems. I really like them nice all mountain skis, SKI AWESOME switch when mounted cab foward. if u need more info PM me
The choppers are insanely stiff - I demoed some in VT and they are a great ski, but really stiff. I haven't heard of any choppers going bad. The stealths were awesome this year.
