In reply to mike kann: This is a hugely interesting topic which i could write a lot about. But basically strapping them as an inverted V is better for swinging than as two parrallel skis.
Big planks are a pain in the arse to climb with. I currently have a pair of 130cm Hagan approach ski's with super-light (and breakable)climbing boot bindings, and a a pair of carbon fibre 150cm Hagan's with slightly better (heavier) Silvretta bindings. These are much better to climb with, but obviously much harder to ski. Yet easier than snow-blade type things some people attempt to use.
I think dragging them is a bad idea. It would cause all sorts of other issues, you just have take your time when climbing a little more technical stuff. But for so many routes its fine, stuff with no technicalities like north face routes on Les Droites, Verte and Courte. In fact half of the routes in Chamonix!
Its something you really have to experiment with, and is expensive to perfect. But climbing up something, and skiing down, with as little sacrifice as possible in both areas is possibly the coolest thing you can do in the mountains, so its worth it!
