Yep. the 3 factors for binding adjustment are Height, Weight, and boot
sole length (BSL) I normally specify tupe 3 skier as well, and just
leave them at what the shop sets them. With Look/Rossi bindings, I've
never had my skis release when I did not want them to, or in a small
fall. Always better to be on the lower side than the higher....popped
off ski > toasted knee.....obviously.
To to OP....whats your boot sole length?
