Listen up, know-it-alls, 4FRNT's binding was originally designed by Nordica and was based off nothing except Nordica's original design (I don't know where you guys get this Marker connection, such bullshit).
The binding worked very, very well and had good test results. In fact, it beat out some companies that would make you very surprised.
What didn't work, was the ski/binding "system", or connection, Nordica was trying to implement. For those of you who don't remember, this was called Synergy. It was a faulty connection to the ski, and had ABSOLUTELY NOTHING to do with the fundemental mechanics of the binding.
While Nordica was trying to improve the Synergy system, they were bought by the Tecnica group, which, at the time, owned Marker bindings as well. Rather than continue with the Synergy experiment, Tecnica axed Nordica's binding program (which cost Nordica mucho, MUCHO dinero in R&D), and simply started using a Marker system on all Nordica's skis to improve Marker's market share.
VIST, which had been working closely with Nordica on their World Cup program, then bought the rights to the Nordica binding and began designing beefier versions for W.C. use. These bindings were highly successful.
4frnt, wanting to expand into the binding market, but having the common sense not to try and design a binding from scratch, was looking for proven technology, that could be tweaked to suite freeskiing. VIST had virtually no marketshare in North America, and decided to partner up with 4frnt to produce the Deadbolts.
The Deadbolts ARE different. VIST has worked very closely with the boys at 4frnt on perfecting an already outstanding binding. It's not a paint job, haters. It's a solid piece of equipment with proven technology that works.
One example:
Take the different 4frnt models - the 412, 614, and 816 (the names obviously referring to the DIN range of each model). The 412 and 614 are produced using the exact same chassis as the 816 team/"race stock" binding. What this means is each binding is constructed with the same metal components that make high DIN bindings so attractive and durble. No mas plastic. So you if you weigh 125 lbs., you don't have to get a binding whose DIN goes from 8-16 (which will rip your legs off) just to reap the benefits of the metal used in race stock bindings. Each binding is the same, except the spring ratio. Make sense?
You find me a binding company who has a 12 DIN binding that uses the exact same chassis as their race stock model, and I'll stick a banana in my ass.
That's the deal. And any other "theories" are bullshit.
