Keep in mind dins are that high not to be maxed out. You always want to be running in the middle of your din range. This will help to ensure the longevity of din tension in the binding.
That is why I chose the FKS xxl 180. I run a 14 din and that is pretty close to the middle of the range for that binding.
Concerning the STH, keep this in mind. The ride height on that binding is quite a bit higher than the FKS. This will inhibit stability and make the ride quality more unpredictable.
The low ride height of the FKS, however, really makes a ski feel low and solid particularly when landing jumps/cliffs into variable snow.
I swear by them in all conditions, particularly pow. They have saved my knees multiple times. Some people complain about snow clumping, however you just have to be conscious about cleaning your boots each time before you get in them.
These are easily the most durable bindings I have ridden. I am 215 lbs these days and these things will not break. That is a first for me.
Is that a pole sticking out of your ass? minibus4$
