I'm gonna have to give my 2 cents on this one.
First off, I'm going to give you my brief background. 5+ years working at an on mtn shop, 4 + years with Rossignol Ski Co. (not a claim, I'm just give you my background in the industry)
Binding adjustment should be left to a Certified Tech. Anyone giving out ANY information on how to setup bindings of NS is completely retarded. Seriously. You don’t know what your risking by advising someone on a indicator setting, or how to adjust forward pressure.
Binding company’s such as Rossi/Look/Roxy, or Salomon/Atomic, or Marker, have full time lawyers who have to deal with settlements with bindings, more then you think. They (read manufacture) will back up a Certified Tech, being that they understand and have taken a test on how the certain bindings work. But they wont back your ass up on giving advice over NS.
Lets give a quick example. Say Joe shop guy ( a certified tech) sets a customers skis. The customer, goes skiing, hits a jump, and for whatever reason blows out or doesn’t blow out of his bindings, causing himself to blow his knee. The custy, then tries to sue the shop for setting up the bindings improperly, which is when lawyers will get involved, and more then likely the manufacture of the binding will back up the tech.
Now, same example, but replace "JOE SHOP GUY" with "Dumbass Newschooler.com user" Your not a tech, you don’t know how to properly adjust a binding, and you advise on how to setup a binding to someone over NS. They bust themselves, and you are left liable for what you suggested on setup, which can royally fuck you over (read mega lawsuit).
Even a Certified Tech should not give out information over the Web/NS. To properly setup a bindings, you need to perform a visual test of the products given, Boot, binding, and ski. You cant see they quality of a product over the web, so insist someone brings the skis into a shop to get them adjusted.
Trust me when I say this: DO NOT ADVISE ON BINDING SETUP OVER NS. Leave it to someone who knows what there doing. Do not attempt to adjust bindings yourself. When adjusting bindings, "close" doesn’t count. Close only counts in horseshoes and hand grenades. Not with adjusting bindings.
