Light weight for all things skiing is critical. I know there is debate on this claim - I take it as gospel.
Last night I was setting up some K2 Burnin Luv skis for a friend. Oh my, they were heavy! The bindings were not light and the mounting tracks made the whole setup outrageously heavy.
I have some Volkl Race Tigers (short little slalom skis) with some fancy all way adjustable race bindings. For such a tiny ski, I can barely lift them. I got a pair of a slightly older similar Volkl race skis (with the flat top) and mounted normal bindings (lightweight plastic upper recreational style) and was shocked by how much lighter the skis are. My wife loved the setup.
A couple of years ago I got some Atomic race skis with adjustable bindings. I loved being able to move the boot placement and being able to adjust for different boots. But the bindings were really heavy. I found the spot I liked and replaced the Atomics with some light weight Salomons Wow! What a difference in performance.
One or two grams is not noticeable. But it seems that many of the bindings that you can adjust a lot are pounds heavier than the lightest bindings. I don't need on hill adjustment capability, I just don't want to drill tons of holes in the skis. But I want to be able to move things around (either to change ski characteristics or to fit different boot sizes). A plate that has various holes would be fine - as long as it's light.
What bindings are light and adjustable? Which is the absolute lightest?
