Operation Extreme Redundancy Shall Carry OnNo, and as said above this is not the place that anyone would want to admit it. You probably wont win due to all of the factors that were listed above. Skier ability and installation are key factors. You could argue either way until you are blue int he face but my guess is that the average consumer does not have the time or money to spend on a lawsuit against any binding manufacturer. Your money would be better spent on a good doctor for surgery, rehab, time in the weight room (lifting/running/balance training... etc), new bindings, and lessons. As was said above it is a dangerous sport and i doubt that any arguement could hold up in a court of law, there are just too many variables.
99% of skiers will blame equipement failure before they will blame user error, when in reality 99% of the time it is in fact user error that causes problems. Errors such as skiing beyond your ability in terms of terrain, not skiing with proper technique (can often be very harmful), trying not to fall when the writing is ont he wall that youre going down.... etc etc. A lot of injuries occurr when a skier freezes and refuses to let themselves fall. That is why backwards twisters are so harmful - the skier fights to stay on their feet, and the bindings still have a proper weight distribution on them so they dont know if you are falling or not. In recent years people are getting too used to technology taking over for them (computers in cars and such), I hope that skiing isnt the next frontier in which a computerchip will take over for that big neuron cluster in your head.
