In reply to George Fisher:
I've no idea what they're worth, but I have a pair of these and I wouldn't fancy touring on them. They're a bit heavy and a bit skinny. It could be done, but I'm not sure you'd enjoy the process.
Also, if they have the pilot mounting system (the binding mounts into the side of the ski instead of the top) it might be more of a task getting a touring binding on there?
Its up to you, but I'm not sure it would be worth it.
