ok. we all know that the rossignol/look FKS bindings are what a majority of the pros use. therefore everyone on NS feels the need to buy them. however, what people fail to realize, is that a pro level binding like that comes with its own very unique set of quirks, and they are designed 100% to be used by people who need a binding of that caliber, and are willing to "pay for it".
what i mean by this, is there is a stage in your skiing where you hit a wall with consumer bindings. i do not want to say what kind of problems these may be, but when you hit that wall, you will certainly know it. if you do not have problems with bindings such as salomon S912tis, z12s, look/rossi px/pivots, by all means, STAY WITH THEM! they are far easier to own and ski with, and when something like a brake gets broken, they are FAR easier to repair.
the oldschool FKS on the other hand is a HUGE pain in the ass. every time you fall, the heel almost always needs reset. the brakes are a massive downfall, the forward pressure adjustments tend to loosen, the toe lacks an upward release, which means you have to either accept that sacrifice, or switch it with a different one that does (again, a huge pain in the ass, it requires technical know-how to make sure it all works together).
so pretty much, the bottom line is this:
yes. Rossignol FKS bindings are one of the best preforming bindings in the world. however, that performance is a huge sacrifice for usability, and for 95% of the skiing population will never be able to tell the difference between that and a high end consumer binding, AND they will be far happier with that high end consumer binding.
