start a thread to find a replacement. Working sucks balls, free shit rules. People break skis all the time. Some one must have a lone ski sitting in their closet or on their mantel. I am sure you could trade Karma, or reach arounds for one ski.
of that doesn't work, just mount both bindings on your good ski, and get 10 foot bamboo pole. Viva la mono ski !
good luck bro.
