Nice summary, Jmd. Once it was clear that improvements in rms values translate to very minor improvements in image quality, the only questions are really about consistency and imaging window. For instance, what kind of weight the mount can handle, how much wind, tracking at lower altitudes, lost subs, etc.. I guess that is part of the question I have about Losmandy mounts. Are they sturdy and precise enough that they can be left alone over night with reasonable assurance that most, if not all, subs will be usable in the morning?
As it is, the EQ does really well within narrow parameters. I've learned to work within those parameters and avoid situations that would expose its flaws. But a typical imaging session involves a lot of time babysitting the mount and keeping it within those confines. I'm curious if a Losmandy mount would be more of a set it and forget it experience, or do you have to go to the $7K mounts for that result?
I really appreciate everyone's insights.

In my experience, Night and day difference between my atlas and my standard gm8 for similar scope loads with respect to rigidity.   Favoring gm8.  G11gt is on a different planet.  I have only done short exposure unguided imaging, but the target jumps around more from sub to sub in the atlas than with the Losmandy mounts. 
Others might have different , or better experience.
Hope this helps

Thanks, Jmd. Definitely helps fill in the picture about the differences in the mounts.
Uncle Rod, I've followed your blog about your new GM811G and await your opinions, with bated breath, on using it for AP.
