I had my M6 CLA'd by Don Goldberg a few months ago and also had him install the condenser in the RF to eliminate the flare. I also switched out for the solid metal wind lever. The M6 came back smoother than it ever was. The RF is now flare-free and as good as on the MP. But the shutter release is still not as smooth as on the MP. The M6 still feels a little notchy, which is only a problem when shooting at slower speeds as I don't feel I can release the camera as smoothly as on my MP or M4.
The one area where Leica really bungled the MP is in the eyepiece. There is a gap big enough to slip a piece of paper under so you can see it behind the eyepiece. Dust gets sucked into here. Leica can supposedly seal this area. For all the attention they paid to other parts of the camera in improving it this is a glaring omission.
