I put on a 43T earlier this year and love it. Three things:
1. It doesn't effect starting on a hill or from a stop or whatever, still easy to get going.
2. You don't feel like you have to shift halfway through an intersection.
3. Now I never look for a gear above 6th. In fact on the backroads riding I do I never even get out of 5th. Probably even better on a freeway. Just a little more relaxed overall. I'm glad I didn't do a 44T because it would be even less of a difference...43T is subtle enough IMHO.
