alot of you guys are idiots...shops dont 'mess up' your din by setting it at a 6 or 7...
din is based on the BSL, skier type (I II or III) height, weight, and age.
if they give you a 5-6 or even a 7...that means that the chart that the techs use says thats the rating they fall under...if they set it to a 9 cause little johnny thinks hes cool and he rips his knee out cause his bindings didnt release, then it quikly becomes a court case.
if they set it to what the chart that the corportation supplies (ala salomon, rossi, etc) then all they have to say is that they followed the exact specs from the company, eleviating the blame on the said shop/tech.
at the same time though, it completley depends on what you are doing...you could rate a 6 but in a gs ski your ski will be popin of all the time on the same person so in certain cases crankin the binding isnt so bad.
but someone who is 5'8'' 140lbs should not be riding a 10 in the park lol. unless you are throwing down double cork 14s on 80 foot kickers...then i might see a cause for worry of a pre-release.
same thing goes with cliffs, pow, charging etc.(this was mainly aimed toward the lil kids who think they are cool riding a din of 12)
