My Dad recently bought some demo skis, Line Prophet 90s, and they came with adjustable bindings on them, pictured below. We are looking to save on new bindings so We're just gonna keep them on. I don't really know how to use these. I'm looking to adjust these bindings for my Dad's boots, But I really don't know how. Can someone help me out with how to do this? I'm guessing it involves that screw on the back but I really don't know. Also, how would I go about adjusting the din, and twist and anything else I can adjust for someone who is 6'1" and 165 lbs. for an advanced
skier who doesn't spend much time in the park (no rails, only jumps)?
I'm not really sure what bindings these are I just know they are salomon
