That actually looks pretty good to me but I'm still not exactly clear on what the issue is.
Could it be some asymmetry in footbed length that's causing this (illusion)? I noticed my diode ests seem to have different footbed sizing than my reflex bindings.
Does your centering method take into account board taper?
For what it's worth I think you have an excellent combo there. You may just have to go with feel even if it doesn't look exactly how you want it to.
