I've been using Miche 12-29 cassettes with 10 speed Chorus for at least 30,000 miles. That bike doesn't shift perfectly but it may be because it has over 50K miles on the shifter and derailleur. It still shifts better than my Ultegra 10 speed with 35K miles. On that bike I can see the rear derailleur getting sloppy.
