One of the features that the Look tech rep's use to push was that the binding could be skied at a lower setting than was normal. They claimed it was because Look has a greater amount of elasticity in the toe and would return to center after an impact that would cause other bindings to release.
That's true but the spring has a disturbingly dramatic tendency to pop out if undone past the last detent.
Elastic - elastic - SPROINGGG!
