I Fucking hate this topic as people will defend their DIN as if it was given to them by Jesus himself.
from what I can gather DIN is purely a chart created by Deutsches Institut für Normung
which translates to German Institute for Standardisation.
Which has created this chart for an international standard.
Yet each binding manufacturer has their own version they have printed. not sure exactly the differentials if any.
The real challenge is to find information on how they came up with these numbers?
my intuition would assume that they would air on the side of caution when it comes to the majority of people involved in the sport of skiing which is significant! majority gapers.
I'm sure they would want to be on the safe side of protecting peoples limbs and joints that are affected by such forces exerted on them. And calculate these forces accordingly.
And I am highly skeptical to whether they had any concern or imput of the sport of freeskiing when these numbers were calculated.
My personal opinion is that There should be a seperate chart for freeskiing.
But I could be completely wrong on this! If you are gonna hate on me for this post do so with a transcript of the current iso or something that can back up your argument!
(I am too cheap to buy the documents, so If you can find a link that would also suffice)
Anyway for arguments sake I am 187 lbs, 5'11", type 3+, 301 boot sole.
This generally means I should ski at 11. I ski park at usually 12 or 13 and big mtn. at 15. I still pop out just fine in crashes and am highly comfortable with skiing at this release setting.
It just shits me that this information is used as "gospel" rather than recommendation. I totally stand by it as there can be liability issues with stores selling safe equipment to customers. And there should be this standard for these reasons. But I dislike arguments with fellow skiers about this is some sort of magic relation to their soft tissue in their knees!
