I am currently doing a 4 layer board and the stack is: (from top to
bottom) Signal, GND, Power, Signal. We are trying to decide which layout
is better. The first scenario is to leave a plane off of the signal
layers. The second is put a plane on the signal layers opposite of the
plane it references.   For example on the first signal layer I would
pour a power plane which references the GND and the opposite for the
other pair. I was under the impression that you would want more coupling
between your planes which would suggest the 2nd scenario would be more
correct. Is my thinking on this right or am I way off base on this.
