Alpine guys with their extreme foward stance all have adjustable canting in their fancy bindings, so canting has benefits in foward stance as well.
I used to a be foward stance guy for decades. +30 +15.
Its only in the past decade that I went duck (+15, -9) and never looked back.
Its easier to carve with foward stance, but duck is so much less fatiguing and its easier to switch, freestyle, etc.
