I'd quibble on a few things in your writeup.

1) I don't believe the engine is Atkinson cycle, and the VTEC shift point is right around 3000 RPM.

2) I seriously doubt that you'll see a 5-10 mpg increase with the Bridgestones. Your flat freeway mpg is just about what I get with them.

I wasn't sure about that, and will edit my post. There was some talk about it over at InsightCentral and some there believe it to have different compression/expansion ratios.
