I am at reference width now. I put it at what is comfortable when i'm just standing but as soon as I strap in, it feels weird on my right knee again. My right foot just wants to lift up on the right side of the foot...it just doesn't feel natural having my foot completely flat at that angle. however, i can't find an angle where flat is working for me.
Have you boarded on it yet? Something that feels weird on carpet might feel just fine on the slopes. Keep in mind your knees should be quite bent while boarding and with a duck stance that'll push them out over your feet.
My knees are most comfortable with a symmetrical -9/+9 or -12/+12 duck stance...
