tomPietrowskiWhat bindongs are they i would gues maybe geiffons if they were on line demo skis. If they are griffons then you wont save much weight going to a non demo.
rozboonAs Tom said, if it's the demo Griffon then it's one of the better demo bindings out there and functionally near identical to a normal Griffon with negligible weight difference.
Chances are it's some horrible rail-mount pile of crap though with a 200m tall stand height, in which case kill it with fire and get something better.
tomPietrowskiWhich are they? Do you adjust them by one part in the middle or do you adjust the heel and toe indivually?
if you just adjust the middle tey are the speed and actually are pretty good. I have a pair I use on test skis and they great.
If it's the other type I would either replace or get them converted to regular bindings. A decent shop who deal wit salomon or atomic can probably swap out base plates which will be cheaper then new bindings.
JsNeagleRemount and sell the demo bindings on ebay.
A ski company, rep, rental shop, etc. will likely buy them.
Most people don't realize that demo bindings are actually more expensive than non-demo bindings at wholesale prices, so you'll often find shops buying used bindings.
