I have a big ring of 44 and I use the 11 on almost every ride. I'm pretty happy with 44/28 up front and 11-34 in the back, 9 speed indexed shifting with Microshift bar end, Deore M591-SGS derailer and HG50 cassette. This combination maxes out about 28-29 mph, which is fine for my usage. Smallest gear of 28-34 has not had me walking as of yet. (although, I don't count it out on the several 20% grades around here).
