Hmm... not sure it's even a marginal upgrade. What worries me the most is the downgrade from 10 or 11 forests to 5. That's a big difference if you go HA rushing. Also less good cottageable tiles. But it's a tricky start when SIP also has it's downsides. When it comes to worker stealing, there's two kinds of games. Those that I decide to worker steal in advance (usually anything where I plan very early rushes) and those where I don't. If the decision is to worker steal, I'll go for it and roll a new map if it fails. In games where I haven't made a strict decisions to worker steal I might still go for it if it's a marginal start and I don't mind throwing it away when it fails. But if it's a really good start I play it safe.
