I have been playing with my setup quite a bit this year. I started the season with a 18" stance, 3 degrees cant front and rear (bindings canting towards each other) and maximum toe lift on the front binding and maximum heel lift on the rear.
I have evolved to a 19 3/4" stance, 0 degrees canting on the front and around 2 degrees on the rear binding, my front binding toe lift has lessened and the rear heel lift has remained the same.
I am riding Catek World Cup bindings and like the adjustability, but the lack of a mechanism on the rear bail annoys me when I am unable to place my boot correctly when getting in to the binding.
My binding angles are in the mid 50's, boot overhang determining the angle (my front is about 3 degrees steeper than the rear).
