There's a variety of different flavors of the maple/graphite GG basses before I restarted doing the all-graphite basses. I think those that still have them have the most valid opinions, but they should all have the same internal neck structure.

Not to scale, but should give you the general idea.
Thanks Geoff this is amazing info. Question- does that graphite laminate atop the truss rod run the entire length of the neck? I assume all layers are there to reinforce the neck and stiffen it?
Thanks again!
