Yeah, I'm probably about as "dialed in" as I'm going to get without actually riding.
As long as you are close with the heel/toe overhang, I wouldn't kill yourself about it till you break the gear in a few days or you have a problem engaging one edge or the other. Riding in them will change how your boots sit in the bindings after a few days on the mountain.
But I would also elect for slightly more toe edge overhang than heel. Just not by too much.
