Yeah, bindings generate alot of controversy for a device that has the least effect on performance of all ski equipment. If someone's pants are too tight they are likely to suffer a greater decrease in perfomance than if they have Salomon vs Look bindings. Let's face it, boot's screwed straight into a ski will perform reasonably well.
As a racer for the last ten years I have skied on absolutely every binding on the market. My personal preference is Salomon but that doesn't explain why my 4 pairs of skis have Look, Marker Tyrolia and, yes Salomon binding's on them. My opinion is that you should ski on whatever fits your ski if it has pre-drilled holes on it's plate for a certain set of bindings, this just makes logistical sense. If you have Salomon ski's for example and have a choice in the matter, get Salomon binding's, everyone will think you're cool. If you have a pair of any other brand of binding's kickin' around that will do nicely, mount them, (as long as they are tested to be safe!) and go ski. Do you really care if some Gorb on the lift notices that your binding's don't match your skis, or do you care that you find the best lines, the deepest snow and have the most fun. I hope so. As far as pre-releasing goes, different binding's will have different mechanical functions that effect their spring tension ect, so get your binding's tested in a shop. If you have an existing pair of bindings mounted that work well for you make a comparison with the new setup to see how much force is needed to release the binding so you can find a suitable DIN setting to make you a happy skier. I honestly don't think that there is a superior binding out there. Races are won on different bindings all the time (sure Atomic win's more but that's cuz it's attatched to their skis), big cliff's are hucked with all sort's of bindings, big jibb's are laid down with the same, the landing is the biggest factor in what releases and what doesn't. If there was a superior binding out there, all the consumer group's and ski magazines ect would have discovered it and proclaimed it's superiority already (even if the company didn't contribute the most advertising dollars, so obviously Salomon's aren't superior
). Some binding's break more than others and that's a fact of life. My experience with the current Look/Rossignol configuration is that they have a greater propensity to bust than do other's on the market. If you check out skireview or whatever that sight is, this can be Anecdotally confirmed. Maybe that's why they come with the better warranty than other's. However, the older Look's (Z series) were bomber, and that's probably why they re-released them this year as their top race binding.
If you've made it this far in my rant I will sign off with: buy what you like, get them tested so your DIN setting matches your weight, ability ect, and don't question yourself if you have a bad landing and get injured whether another brand of binding's would have saved you ACL, MCL or whatever it is that you break/tear. I honestly don't think there is a superior binding out there, and if there is, safety and pre-release are a trade off.
Just my $0.02, although it probably sounds more like 10 cents by now.
