I have a 100% lower grille block and 0% upper grille block so I don't have to remove even in the summer. Hottest temp around here is ~85-90 °F. I even have my fire blanket. I remove it when I go in the mountains. But in city its fine with all the P&G I do. I monitor the °FWT on the SGII and it never exceeded 212 °F even with 90 °F outside. The fan does a really good job of cooling the engine.
The more the engine is hot the more efficient it is to cool. So it takes less time to lower more degrees. But sometimes in the mountains I have to evacuate excess heat with the HVAC.
I think the ideal setup is one like MetroMPG did on his Insight, 100% upper and ~85% lower. He even made it "stop-light" adjustable so it was even better.
EDIT : Nice avatar touch-up.
