The mfgs insistence on a top cogs of 11 & 12T is absurd even with compact cranksets except for the strongest racers.
For the 10 cog set-up on my Vitus I bought a CS6600 "Junior" 13-25 and a 5700 12-27, by using the bottom 3 cogs from the 5700 I now have a very useful
13-14-15-16-17-18-19-21-24-27 and a spare 12-25.
I raced on a 107GI top gear "back when" and don't need anything taller now.
Since the 11 cog systems are 11T top for any mid/wide range cassette they offer no advantage for me.
edit: Back when shops had a Cog Board to build custom FW or Cassette as required and replace worn single cogs at little expense, too old fashioned and labor intensive today.....
