So your first question if you are in the US is what is a Supercross 9:2? I would love to know more, but all I can tell you is that it was only available in Europe and NZ. Stiffer than a 9 and less so than a 10? I dunno, but its a fun ski.
But it has Device 311 bindings. They were manufactured 2004 and thus not subject to the recall, but also no longer indemnified.
Should I replace them?
Assuming I will get a lot of yes answers, with what? Anything using the same holes thats indemnified and/or safe?
Alternatively, a friend has a pair of Salomon s711 he'll give me. How hard would it be to make those work.
I've never mounted bindings before, but I maintain my own skis and have ski vices. Generally good with tools.
