yeah. if the springs inside the binding are either at maximum or minumum tension, it's not good for the binding. your din setting should always be somewhere around the middle of the binding's range.
so, if you're a light fella and want your dins around 6 or 7, get a 4-10 binding
if you want your dins around 7-9, get a 4-12 binding
if you're a big mofucka and need your dins around 10 or something, get a 6-14 binding.
you should rarely need dins any higher than that unless you're going to be hitting like 90footers and are a really big guy. your bindings certainly wouldn't release, but i'd be more worried about my knees having the bindings set too high than stomping a landing
