If we settle on green, we can barely get a 2 turn worker factory at size six, if we have no corruption until six spt. With commercial, large, and 2 distance from capital I don't think we'll have a corrupted shield until six. Then maybe a town 2 S of that to grab the whale.
I'd do capital 6644, that avoids food waste.
