Having slept on it...
Having made the mistake of playing Agriculture first and still getting Poly, I think we have some turns if we wish to use them, although I would not go past turn 2 or 3. Think it also depends upon what wonders we think we want/need.
In the settle on Marble trials, it seemed possible to get Oracle, Stonehenge, 'mids, Temple of Artemis (+100% trade routes) and AP. Settling 1E did not develop fast enough to do all this. We would need a good second city site, founded quickly, to do all this. Once we start building Oracle and 'mids in the capital, there isn't much time for settlers and pop-rushing delays production.
If we find any food resource south of the Marble Hill, I think it will be worth settling there. Should there be further resources north of the Stone, that makes it even more attractive.
I am leaning towards a trip to the Marble hill and a further decision from there?
edit - forgot to ask about this:
Don't forget spies, Kakumeika used a few nice tricks last SGOTM.
What tricks did you learn?
