I added a link to previous post -
This all started when thru a discussion about "snapping" on a model - One writer noted that forward CG INCREASED snap tendency -and also -- too much rearward CG increased snap tendency - it then went into the theory that a forward CG increased wing loading -which I would not buy -
this linked page held the explanation -which I saw and still see as only an analogy -in that the real change is simply efficiency due to changes in trim drag required to hold AOA.
