+100 and if you buy the Veloce level they are very reasonably priced too. My favorite Shimano 10-speed cassette is the 12x27 and at the 105 level is also pretty low cost.
For road bike use with a typical 52 or 50T big chainring, I have little use for a 12T cog and none at all for an 11T so I wish there were more 12xXX or even 13xXX cassettes. For most riders an 11T cog only makes sense for MTB use with their very small "big" chainring.
