Switching to 10 speeds was the best thing I ever did. I went from a 28/42/54 and 11-32 9 speed using Campy 10 ergos and a DaVinci modded rear Sram to a 26/39/53 11-29 full Campy using a Long Cage Campy rear derailleur and Campy Veloce rear cassette (single cogs allowed me to create the 11-29). If you plot the gears - you'll see less crossover, less gaps more usable gears and a high and low near identical to what I had before. Shifting is MUCH improved as well.
