I have used the Pilot classic bindings for some of last season and all
of this (358km of classic so far this season, I keep a spreadsheet
which makes me a nerd, but a nordic nerd!). I ski in western Colorado
at an elevation of 10,000+ feet. This has been a cold and snowy winter
in the Rockies with 7 feet of snow on our trails. Anyway, I have had
near perfect performance from the bindings. Once or twice, the hook
unclicked from the back bar, but hooked right back in. I have read
that Kikkan Randall had some problems in a race. They seem like a nice
binding, but I would live with the bumper Profils if I had it to do
over again. The difference is subtle. The new Salomon boots, on the
other hand, are wonderful and worth every penny.

What are you all using for a binding lubricant?
