> can't you just inoculate your starting culture with a larger amount or something
No, I'm doing high throughput cloning in such a way where a limiting factor is going from 1 cell to X cells (usually pickable colonies). So liquid culture doesn't matter quite as much, since I can sequence validate from a colony split (half into colony PCR, half into new culture), and sequencing takes approximately as much time as the growth step takes.

Eh, not really. The biggest tradeoff is that it isn't studied nearly as much as E.coli, so the chemical competence protocols kind of suck. I can't actually use it in my pipeline right now because of that. So I'm stuck with E.coli until I can figure out a good transformation protocol.
