With all the discussion about ACL injuries, binding designs and function, one of the things that I noticed is that very few actual mention what settings that they use.
Some of the members that I have PM'd with actually use higher than expected based DIN's on binding selection and as there is overall a mortal (classified as non WC Racer in prime of life/training) setting upper limit at about 12 based on wt and small BSL.
That said, what do you use as criteria?, and is a guide or a bible?
A little reasoning ideally should be given for what you are doing. IE "I exceed 3+ rating on this type of binding because......"
This is more to see the justification and not to judge any ones methods as they work for you or you wouldn't be doing it.
