Thanks for this in depth report. It was really helpful. I guess I'm just generally out of luck with my dream of a 28 tooth chain ring, unless I pretty much want to start over.

I'm thinking that I'll get a Shimano Tiagra 12-30 cassette. That will give me the 1:1 I think need for a big double century with a ton of climbing. I know i won't miss the 52-11 gear. The Tiagra weighs more than the Ultegra, and more importantly lacks the cool factor, but really, who will notice other than me? And as a bonus almost all the middle gears remain the same.
