Any ski techs out there? I know the industry line is to have bindings adjusted by a trained tech, which I have always done. Anyone do it yourself, or is it possible to learn on your own? Any opinions or do it yourselfers? The DIN setting is a factor of weight, height, boot size and skier ability, correct? I found websites that claim to have the formula for computing that. But how do they determine the actual length to set the binding at? I’m not talking about mounting the bindings, just adjusting existing.
