Curious . . .
It is hard to say how much parralax we are experiencing, but the last link in your latest message has a photo that looks like the tailpiece is mounted off center of the neck. Although tailpiece (slot) position is important it does not define where the bridge aligns the strings to the neck.
You are saying the the G "can" roll off the neck, but does it really roll off the neck to the point of being a nuisance? I CAN roll my Distillate's G off of the neck, but it is not a problem . . . . unless I am sloppy drunk when playing (which embarrassingly enough has occurred in the deep dark past - I like to think I am more mature these days). Then that is not a string alignment issue, it is the interface between brain and fingers . . . .
I digress - have your frets redressed and see if the buzz goes away and then convince yourself that everything doesn't have to be symmetrical to be beautiful.
