i found i had a ski where the drill holes lined up with the skate deck...sometimes people damage a ski and might be willing to part with a single ski fairly cheaply
Just checked your first vid. Sick. I don't really pay attention to snowskates. Nobody I know does it around here. Your vid made me want to try a longer ski, badly! So sick, actually looks fun and manageable in terms of steeper slopes and scrubbing speed when you need to. Super rad!
