This season I bought a new pair of skis, the Head JO pro 2008 model and i have skied on them for only 1.75 months and they are broke. The edging is cracked and coming off right under the back side of the binding area. Also the core is somewhat cracked in that area. I do grind rails and hit jumps but nothing out of the ordinary. Anybody have a clue if I could use my warranty to get a new pair? The skis were ordered directly from head.
