My Campy 12 setup has a closely spaced 11-34 with a 48/32 crank. It's a straight block up to the 17, then 19-22-25-29-34.
Depends how fast you are going. Im using a 11-34 for commuting and I never notice the missing 14t and 12t compared to a 11-28. 50/15 is plenty for 25 mph and the 11-34 allows me to stay in the big ring for longer. I quite like it. Less wasted (too) tall gears in exchange for a more useful lower gears.
