For me, the highest gear I can effectively use for any extended length of time on flat ground is around 85 gear inches. If I go higher than that, my cadence slows down, I feel like I am going faster, but my speed doesn't actually go up. And I don't think of myself as a slow rider. So even having a 40/11 is not entirely necessary for me. Plus the small cogs are not as efficient. It is nice to have a higher gear when you are going downhill and want to rest a bit, and pedal at a lower cadence so you keep your balance. A lot of this is theoretical.
The cassette is 11-13-15-17-19-21-24-28. It cost around 30 dollars and it seems to be a good cassette. The 15 matches up with where I usually like to do most of my riding, and it is a good chainline with the big chainring so it rides smoothly and quietly there. I enjoy planning these things, I don't know how many times I have used Sheldon's Gear Calculator ( and how many times I have forgotten to select "gear inches" and have the results come out in "gain ratio" ) but there are a lot of options that would have worked fine.
