I think you should ask questions of the conventional wisdom. The conventional wisdom says one of the reasons to move a company to the Bay Area is that it's easier to hire developers. You should question whether that's really true. I gave some reasons why I think it might not be, and cited my experience. I don't think it's true. But you make the call.
Also, careful with words like "later stage". You're "later stage" as soon as you hire the first person who isn't getting a founder's stake in the company. For us, that was weeks, not months, after the birth of our company.
