I find that strange that you say 12 speed is more difficult to keep tuned than 11, as I've been running the Shimano 12 speed for about a year and a half, and have never had a system work so flawlessly without being Di2. My gears shift always and perfectly. Mind you, I have XTR shifter and derailleur, but with an SLX cassette. I literally never have to adjust it, and it is the best mechanical shifting I've ever seen. I do ride very hard, blacks and double blacks, and I won't hesitate to recommend any of the Shimano 12 speed groups. Definitely quality stuff in my eyes.
