Someone that knows something about bindings please help

yea its the same

its the same but the 8-18 will be heavier

no difference, but i THINK if you were comparing older bindings it was ideal to have the DIN somewhere in the middle of the range so as to not exert too much pressure on the spring - current technology took over this and now anywhere in the range is generally ok..

anyone care to clarify this?

that sounds about right, but if you know that you will be skiing a din 10 for sure, I would still go with a binding where 10 is not at an extreme just to play it safe.  but it really shoudln't matter anymore

I can't remember what DIN stands for, but it is simply the setting of the spring tension.  Whenever the force of your boot on the bindings exceeds the force tension of the spring, the binding releases.  So, the higher the DIN, the higher the tension on the spring.

If a 4-12 DIN range binding is set to a 10, it is proportionally putting more tensile stress on the spring compared to a 10 setting on a 8-18 range binding.  So, it is true that the spring in a lower range binding will wear out faster than a higher range binding.  However, the release and performance SHOULD be the same if the bindings are both relatively new. 

I hope that was helpful.

yeah, thats some good info, thanks man.

the quality on lower din bindings generally isnt as good as the quality on a higher din binding. normally more metal and all on a high din binding.

you can often double the cost too..

with new bindings, durability is generally reflected in the price

wow, I never knew how a binding actually worked before. this coincides perfectly with my physics test on springs tomorrow.
