If you can figure out a chainring/cassette combination that lets you do most of your flatland riding in the middle of the cassette, you can minimize that issue.
seems you answered your own question, this is exactly what i'm trying to do, instead of jumping from little ring to big ring all the time, i want to get a faster 11-28 cassett so i can stay on the 39 longer on the flats, instead of jumping from little ring to big ring every 5 minutes on my 12-25 cassett. The reason i don't want a standard 11-23 or something is cause when i do hit the odd hill (my 1km driveway) i want the 24 and 28 climbing. The 49 or 50 big ring was just something else i was tossing around.
