This was my first thought. If you're rolling one week out week after week, you're keeping yourself in the highest theta decay "region". You are also holding maximum leverage, however. So yet again, pros/cons.
There's a special case though: if all you want is to capture a step up in the stock price, never allowing options to get within ~30 days of expiry will minimize effective theta decay. I think this matches @KarenRei's thesis.
Also, doing it when the SP is higher reduces rollover transaction costs, as the bid/ask spread tends to be a lower percentage.
