With the outlook being several days of cloudy weather I braved poor conditions tonight to test the DM-6 with my newly acquired C11. The upshot is that I didn't have any trouble making minute adjustments so cleaning the discs appears to have worked.

I did notice that the AZ motion is entirely smooth and controlable when the top metal disc is turning against the white plastic (these were in lockstep before cleaning), whereas there was still a hint of striction if the bottom metal disc turned against the white plastic. (I could get the white plastic to turn against either metal disc by holding my thumb and forefinger against it). Under normal operation the top metal disc always turned first against the white plastic, so small movements/tracking are free of striction; the bottom metal disc would also begin to slip against the plastic when the mount was moved faster. Overall I get very smooth operation in both axes now.

I tried using the C11 with and without balance weights for the AZ axis and found that the AZ motion was much nicer with the balance weights. I wasn't at all surprised by this given the weight and width of the C11.
